Dirk's Piano Tuner

Tuning a piano the classical way is a very complicated process. One has to possess the skills, to handle the tuning hammer in the correct manner and to leave the tuning pin in a stable position. It is however even more difficult to determine the correct pitch of the strings. Many instruments can be tuned using a simple tuning device. Each tone is then tuned exactly to a predefined frequency. This method can't be used tuning a piano. The result would make the piano sound harsh and out of tune. The reason for this lies in the way stringed instruments produce their sound. Dirk's Piano Tuner analyzes your instrument and uses the results to calculate the optimal tuning for your piano in particular. Using this calculated setting, you can then tune your piano, in no time, to a professional level, without having to go through the classical, time consuming, process of 'checking the intervals'.

How to tune a piano

Course week 'piano tuning for beginners'
The course is given in the Dordogne in France. During the course you will learn the theoretical and practical steps of the piano tuning process (with the help of Dirk's Piano Tuner). For more information, click on the following link:

Course week 'piano tuning for beginners'

A string can vibrate in several ways. It can vibrate in one whole section; the middle of the string then oscillates and the ends are fixed. It can vibrate in two sections; the middle and the ends are then fixed and the string oscillates on 1/4 and on 3/4 of the length. This way a string can also vibrate in three, four, five... etc. sections. All these vibrations occur at the same time in the string. Each vibration has its own frequency. A struck string therefore provides several frequencies at the same time. These are called the strings' harmonics. When these harmonics are exactly 2, 3, 4 and 5 times the base frequency, then a simple tuning device can be used. For a piano this is unfortunately not the case. For a piano these factors are not exactly 2, 3, 4, and 5. The exact values of these factors determine the base frequencies of the piano strings, that is when the piano sounds most harmonic or 'in tune'. In practice it shows that the low note need to be tuned a bit lower. The high tones need to be tuned a bit higher. The rate in which the low notes need to be tuned lower and the high notes higher is called the stretch of the piano. This means that each piano has to be tuned differently to achieve its optimal sound and performance.

Determine the right stretch
There are already tuning devices that take this stretch into account You can choose a stretch at setup, where a small stretch is chosen for a large piano and a large stretch for a small piano. Such tunings devices can take the piano to an almost optimal tuning. But the specific design of the concerning instrument is not taken into account and therefore some of the factors, that decide the stretch, are left out. Because of this, the piano will not sound optimal and it will still be necessary to determine the best stretch 'by ear'.

The piano technician does this by striking a lot of intervals (two keys at the same time) and aligning them. To do this properly, a lot of experience is an absolute necessity. The difficulty lies in the fact that you cannot tune the intervals entirely pure and the rate of purity is different for each and every interval. When an interval is not entirely correct, one of both notes will be adjusted accordingly. This note however is also part of several other intervals. Therefore all these intervals will have to change as well. All this produces a large complex puzzle that has to be solved.

Dirk's Piano Tuner solves this puzzle for you. In Dirk's Piano Tuner all strings will be recorded by playing them all one by one, only one string per note the remaining strings muted. The tuning (and so is the stretch) is determined by the computer using these single string recordings. The tuner not only records the fundamentals, but also the harmonics. After this 'single string' recording, the tuner has all the data needed to calculate the optimum base setting of all strings. The tuner calculates then the purity of all possible intervals and aligns them. After this the strings can now be tuned one by one to the resulting notes from the tuner. The tuner recognizes the struck string automatically and shows how much the string deviates from its ideal pitch. The muted strings are lateron tuned equal to the earlier tuned string in the same unison. After tuning all strings the piano has been tuned with the best stretch. The piano now sounds as pure as possible for that particular piano. Each note needs only to be tuned once and it is no longer necessary to finish the tuning by ear.

Comment: Un SAV de Qualité.
Petit mot concernant le "service après vente".
Après avoir eu un problème d'ordinateur et avoir perdu le logiciel. (Presque sans avoir eu le temps de l'exploiter).
J'ai eu très peur d'avoir fait un tel achat pour rien.
Il m'a fallu l'instant d'un E-mail et d'une réponse le lendemain même pour tout résoudre. Plus d'inquiétude.
J'ai réinstaller Dirk's Piano Tuner, et je n'ai plus qu'a trouver un moment de libre pour accorder mon Piano.
Merci Dirk.
Dépannage très satisfaisant.

Comment: Der Pianotuner ist hervorragend. Die Software ist einfach zu installieren und zu bedienen und die Unterstützung durch die grosse Frequenzdifferenzanzeige beim Tuning ist vorbildlich. Bei Fragen und Problemen reagiert Dirk innerhalb von einem Tag.
Mein 160-jähriger Blüthner Flügel war nach dem Tuning mit Spreizung nicht mehr wiederzuerkennen. Er hat jetzt den phantastischen Klang, den man von alten Blüthnerflügeln erwartet.

Ich kann den Piano-Tuner und die gute Unterstützung durch Dirk sehr empfehlen

Comment: Great software. Easy to use. The results are better than the aural tunings I've done and even the professional tunings I've paid for, and after several tunings the software has paid for itself. I had a couple technical difficulties, but each time Dirk responded almost immediately by email and solved them. Great service! I'd recommend this product to anyone.

Comment: Greetings.

I purchased Dirk's Piano Tuner software and went through the video tutorial. I carefully tuned my piano using the software, and the result was the most perfect tuning ! The piano sounds just beautiful, every note exact. Dirk says that one can achieve professional results, and I agree that's correct. I believe my first tuning using Dirk's Piano Tuner actually achieved better than professional results.

I will always tune my piano myself from this point forward, and I highly recommend purchasing Dirk's Piano Tuner !

Comment: I was tuning a grand down in the south of France and Dirk was very quick to provide emailed assistance when I had a query about a technical matter.
On a different matter, going through Gatwick and Marseille airports with a tuning lever in my hand-luggage was a somewhat problematic because it aroused the suspicions of the chaps manning the X-ray machines, and I almost had it confiscated both times because of it having the potential to be used as a weapon; but when you are only travelling with hand-luggage, where else can you put a tuning lever?

Comment: I purchased and tried the Dirk Piano Tuner yesterday. It's easy to work with and I find it very efficient. The result was a Piano nicely tuned in Equal temperament. I did some "blind tests" to compare a purely aural classical tuning (the main consonant intervals by ear) against the Dirk's Tuner tuning, the deviation bracket between both methods was quite big. After playing some pieces on the piano (I'm a professional pianist), I got truly convinced that the Dirk's Piano tuner's tuning was far better than the aural tuning.
This is one of the cases where technology innovations go beyond the human performance. Dirk's Piano Tuner saves lot of time and eventually gives a better result compared to the too subjective human aural perception.
All this might be true only in Equal Temperament where all the tone frequencies are evenly distributed along the keyboard compass. In future I'd also try other temperaments with this tuner and will share my experience.

I'd highly recommend Dirk's Piano Tuner to all professional tuners and performers (like myself) who want to tune the instrument by themselves.

Thank you, Dirk!

Comment: Software spettacolare!
Muovo i primi passi, dopo aver seguito per anni il mio accordatore e studiato recentemente kirnberger e l'equabile. ho acquistato chiave e smorzatori e mi accingo ad intraprendere questo affascinante percorso su un piano completamente scordato ma con le caviglie in buono stato. Senza il Dirk sarebbe difficile anche provarci, ed una mission impossible far quadrare tutti i conti!

Comment: Bought this software yesterday. I had a few issues as i made a mistake when installing the software. Emailed Dirk and got an immediate response. He guided me through fixing my problem step by step. Great service.

Tuned my first piano with the software today. Have been aural tuning for a long time and was totally blown away by the results. Have hated every other bit of software ive ever used for tuning. Thought this was amazing. Had a completely out of tune rustbucket tuned in an hour and a half. id imagine as i get used to the software i should be able to bring that down to an hour. Really recommend this software. It really is the best out there

Comment: I am amazed at how this software manages to deal with tuning a piano, what with determining the stretch and getting the temperament spot on.

I tried many tuning aids in the past and none were able to tune the piano to a professional standard.

The mechanics of the tuning process need to be mastered but if you can get each note really close to the optimum pitch and tune in such a way that it will stay, the results are really excellent.

expensive, yes, but worth every penny (or should I say "cent")

Thanks for designing the software..........

Comment: I have had the tuner for nearly a year and am very happy with it. I use it to tidy up my pianos between professional tunings but will soon have enough confidence to do a full tuning myself. When I had some questions, Dirk responded quickly and was very helpful. The same was true when I needed to replace my computer. I would certainly recommend the tuner.

Comment: Fantastic and Beautiful tone Result! I tuned an old used Kimball spinet Piano to a beautiful Perfect and bright sound (along with repairs of stuck and twisted keys and lots of dust). I attribute the strong beautiful sound to the "STRETCH" function of the Piano Tuner program. The science put into this software to isolate the "sound-board's signature" of harmonics creates the perfect "Human Perceived" correct pitch tuning of notes.
Thanks for striving for perfection.
Thank you very much!

Comment: Ich bin ein leidlicher Amateur Klavierspieler. Auf einem leicht verstimmten Klavier habe ich gar keine Lust zu spielen. Alleinige Versuche, die Stimmung zu verbessern, waren nicht wirklich erfolgreich. Die Theorie ist für mich auch zu schwer.

Dirk's software ist eine tolle Sache. Der Flügel klingt wirklich gut. Der Kauf hat sich gelohnt.

Der Support ist auch sehr gut; Installationsprobleme mit einem älteren ASUS wurden schnell und kompetent erledigt.

Thank you, Dirk.

Comment: I tried twice tuning by ear and the first time was not too bad. The second time turned out way worse than when I started. I used Dirk's piano tuner and tuned two pianos now that are as good or better than if I paid someone to do it. Now I can tune my piano every few months or so. It now is a pleasure to own and play a real piano. Previously I only liked playing my Software Pianos (Kontakt) because they always stayed in tune.
Thank You Dirk for the software.

Comment: Dirk's Piano Tuner and Dirk's Projects Piano Tuning School with Ben Verbon helped me to get in piano service business!
This program is cleverer with each edition. I remember how Dirk improved the jumpy needle and many other things are being polished with every update.
I am happy to use this smart software. It is doing the mind job a highly qualified piano tuning technician. My customers are happy with the overall sound of the piano after my tuning. Sometimes when the microphone is not capable of capturing the note I tune it by ear. But the base of the interval stretch is done by this wonderful program.

I have heard about many piano tuning devices invented in the US. But I like Dirk's Piano Tuner for the following reasons:

1. Acceptable price (compare the price of Verituner $1.500)
2. The fact of requiring ALL notes to be recorded. 5 notes is not enough EVER to calculate just anything. 88 notes - yes, it is enough. (there is something in being a dutch-generated software!!! It is accuracy.)
3. It requires you to be good. No failures. If the note recorded bad - you have to redo it. period. You have to be good. Otherwise you cannot use this program. So, the DPT maintains a high quality approach in tuning.

I recommend this software to anyone, whether you want to start tuning pianos or if you want to test if this program really does the job.

Comment: Je me dois de vanter ce logiciel pour l'avoir perdu deux fois en deux ans et le récupérer le temps d'un courrier puis pour ses qualités bien sur.

Il existe bien des façons d'accorder un piano, en cherchant les meilleurs compromis relatifs à l'inharmonicité de l'instrument, et si cet art reste réservé aux accordeurs professionels ce besoin de précision ou plutot de style particulier d'accord ne concerne finalement que les musiciens avertits.

Pour ma part je ne suis q'un pietre pianiste amateur ayant fait l'aquisition d'un piano à queue de petite gamme, avec un budget plutot limité, et désireux d'avoir un piano qui sonne juste et agréablement. J'ai tente des accords à l'oreille. IMPOSSIBLE. C'est vraiment un métier. Je ne sais pas quel type d'accord calcule Dirk's piano mais le résultat est excellent. De plus le confort d'utilisation est bien pensé. Le défilement des pics ou du curseur du Vumetre sont l'idéal pour un bonne harmonie entre l'action sur la clé et le résultat de celle ci. La précision du curseur et sa réponse instantanée à l'action de la clé m'ont fait comprendre les vrillages de la cheville et le calage de l'accord.

Pour parler des pics, on peut même voir les trois cordes d'un meme coeur en meme temps. Il m'arrive d'accorder à la seule vue de ceux ci, en faisant sonner en meme temps tout le choeur pour un accord rapide. Pour conclure, n'importe qui peut accorder un piano, et bien, avec ce logiciel qu'il sagisse d'un accord complet ou d'une maintenace régulière.

Comment: Hab vor 3 Monaten ein gebrauchtes Yahama U-1 erstanden. Nach einem halben Jahr haben sich die ersten Verstimmer eingeschlichen. Nach kurzem Suchen und längeren Überlegen hab ich mir diesen PianoTuner geleistet. Vom Ergebnis, auch von mir als Klavier-Stimm-Laie, bin ich begeistert. Der Kasten klingt perfekt und ich hör auch über die Intervalle und Oktaven nichts, was auch irgendwie verstimmt klingt. Der Umgang mit den Stimmuntensilien wird das nächste mal besser, der ganze Stimmvorgang wird dann in 3 Stunden erledigt sein.
Vielen Dank, Top empfehlung! Wird sich im Laufe der Jahre rentieren und Freude bereiten. Ausserdem kenn ich jetzt das Innenleben meines Klaviers.

Comment: Ben nu bezig mijn piano te stemmen middels Dirk's Piano Tuner. Fantastisch stukje software en gemakkelijk in gebruik. Afgezien dat het stemmen op zich natuurlijk de nodige techniek vraagt werkt de Stemsoftware probleemloos. Als 1 snaar al van zichzelf zweeft is het lastig stemmen maar dat ligt dan niet aan de software. Complimenten voor de harde arbeid van dit prachtige "gereedschap".

Comment: I am an amateur piano player but I would like to keep up my piano tune every 6 months. I hate to play my piano when it is out of tune. It cost so much money to keep the piano in tune if I don't know how to tune it. I decided to purchase Dirk's piano tuning software so I can tune my piano by myself. The Dirk's tuning software was impressive me because It took me less than 3 hours to get the piano tuned as the first time. I give Dirk's project tuning software a thumb up for his excellent work. And, the good thing is I don't need to have the piano tuning technician to tune my piano anymore.
Thank you again.

Comment: Hiermit reihe ich mich offiziell ein in die Liste der Begeisterten des Piano-Stimmprogramms (vorliegend in Version 4.0). Folgende Argumente hatten mich bewogen, dieses Programm zu erwerben:

- Das Programm misst die Streckung für ein Piano komplett über alle Töne aus. Im Gegensatz dazu verwenden Stimmgeräte, so sie denn überhaupt individuelle Streckung anbieten, in aller Regel lediglich einige wenige Stützpunkte.
- Das Programm konzentriert sich auf das Wesentliche - das Stimmen eines Pianos / Flügels in gleichstufiger Stimmung. (Wer braucht schon Werckmeister und Co?)
- Ausgehend davon, dass man bereits einen (möglichst mobilen Windows-)-Computer hat, ist das Preis-Leistungs-Verhältnis besser im Vergleich zu einem spezialisierten Stimmgerät.

Gestern habe ich dann zu ersten Mal mein Piano gestimmt. Und was soll ich sagen: Es hat funktioniert, einfach Klasse! Innerhalb von vier Stunden war die Messung / Stimmung durchgeführt. Das Piano klang danach erheblich brillianter und ausgewogener als zuvor. Bravo! Bei dem Piano handelt es sich übrigens um ein Kleinklavier der Marke Mannborg. Bei einem solch kleinen Piano ist, denke ich, die richtige Streckung besonders wichtig.

Es sei erwähnt, dass ich bisher über keinerlei praktische Erfahrung auf dem Gebiet des Klavierstimmens verfügte. Zusammen mit dem Programm haben mich lediglich der Wille, die Sache selbst in die Hand zu nehmen, sowie die Höhrerfahrung früheren Spielens auf einem Streichinstrument ans Ziel gebracht.

Jedem, der sich mit dem Gedanken trägt, (s)ein Klavier selbst zu stimmen, kann ich nur empfehlen, sich von Klavierstimmer-Esoterik nicht abschrecken zu lassen. Jeder normale Mensch kann so gut höhren, dass er Oktaven und Primen (Chor-Reinheit) locker auf Reinheit bewerten kann. Und die Benutzung eines Stimm-Hammers am Klavier erfordert lediglich etwas Feingefühl und wenige Grundregeln wie z. B. das Setzen des Tons von Hoch nach Tief. Der Rest ist Übung. Mit dem Stimmen (und auch Regulieren) aus eigener Hand habe ich jedenfalls ein viel besseres Verständnis für mein Instrument entwickelt. Jetzt weiß ich, warum welcher Ton so klingt, wie er klingt, und ob man da noch was verbessern könnte.

Danke also noch einmal an die Schöpfer des Klavierstimm-Programms! Ohne das Programm hätte ich mir das vielleicht nicht so leicht zugetraut. Jetzt freue ich mich schon auf die nächste Stimm-Runde...

Comment: Хочу выразить слова благодарности разработчикам программы по настройке пианино. Я, не являясь профессиональным настройщиком, приобрел программу для личных нужд, настроить пианино дома, на даче и. т. д. После получения полной версии, научился великолепно пользоваться интерфейсом и качественно настраивать самый "убитый", расстроенный инструмент. В процессе использования программы, несколько раз возникали технические вопросы (переустановка Windows)и. т. д, которые Dirk решал буквально за один час. Программа работает великолепно, и не требует каких то совершенных знаний по настройке. Просто нужно изучить немного теории, почувствовать программу и инструмент. После окончания настройки, ВЫ получите настоящее удовольствие от того, как зазвучит инструмент, а также кайф от проделанной Вами работы. Лично я очень доволен. Хорошая фирма и классная программа. Желаю разработчикам дальнейших успехов и мирового признания. С уважением Гавриш Александр

Comment: Ich kann das Klavierstimmprogramm absolut empfehlen. Leicht zu bedienen, die Stimmung mit Spreizung sind nach meinem Gehör voll überzeugend. So schnell und sauber konnte ich noch nie meinen Flügel stimmen. Der Support ist top, prompte Reaktionen, egal, ob spät abends oder am Wochenende. Einen Wunsch hätte ich noch: eine Möglichkeit der Anzeige für gleichmäßig temperierte Stimmung.

Comment: I had an older upright where the pitch was a halftone down overall, plus it was out of tune. After checking out the trial I downloaded the full version. I increased the pitch of the upright "by ear" by a halftone, and of course it was totally out of tune afterwards, then I started using the software. The recording part took a while, maybe because I used a very simple mic from a headset, probably not the best choice, but I did get it all recorded eventually. The tuning itself worked like a chime and I am very impressed with the result. I play the piano since 40+ years and to me the tune of the piano sounds very good. Maybe a top-notch tuner could have done a slightly better job by ear - I don't know. But we're not talking about a concert grand and for the task that needed to be done Dirk's software was the perfect solution, in particular because increasing the pitch means most likely I'll have to do a couple follow up tunings very soon, which would be very costly. Thanks Dirk for a great product!

Comment: De Piano Tuner werkt prima. Zoals de instructiefilm toont, zo gaat het ook. Wat je wel moet leren is de stemhamer hanteren. Want de stempennen moeten wel zo achtergelaten worden dat ze niet verlopen. Dat is zoeken en vereist Fingerspitzengefühl. Maar dan heb je me toch een mooie piano terug! Ik kan het iedereen aanbevelen. Het is ook leuk om te doen. Groeten, Hans Zijderveld

Comment: Je ne puis que chaleureusement recommander cet accordeur de piano, comme je l'ai déjà annoncé, jamais mon piano n'a eu un aussi bon son et cependant il a toujours été accordé par des professionnels, jamais plus je ne ferai appel à eux. En outre le service après vente est tout à fait impeccable, je viens d'en avoir l'heureuse surprise suite à un problème de PC, tout de suite très rapidement dépanné. Franchement je ne regrette pas mon achat!! Michel IGNACE

Comment: Hallo Dirk, vielen dank für das tolle Stimmprogramm. Ich besitze es jetzt schon ein halbes Jahr und ich kann nur sagen: Top! Die Berechnungen für die Seitenstreckungen sind stets korrekt. Das Programm ist eine wirkliche Erleichterung für das Stimmen und erspart einem - nach ein wenig Eingewöhnung in die Funktion des Programms - viel Zeit im Gegensatz zum manuellen, konservativen Stimmen. Genial ist die Funktion, dass man sich einen "Kundenstamm" speichern / anlegen kann und nur einmal das Klavier aufnehmen muss. Anschließend kann man die Aufnahme immer wieder für Folgestimmungen verwenden. Fazit: Preis- Leistung ist Top! und auch für Laien geeignet. Für professionelle Stimmer in jedem Fall eine Überlegung wert! Vielen Dank und viele Grüße aus dem Sauerland

Comment: Très enchanté, et très surpris du résultat. Vraiment !! Pianiste amateur mon piano a toujours été accordé par des professionnels et JAMAIS il n'a eu un si beau son, c'est déjà bien qu'il soit juste mais là la surprise est totale, son juste, clair et bien coloré, tout y est ! Désormais plus personne n'accordera mon piano à part moi. vu le prix et à la retraite j'ai un peut hésité, dans un premier temps j'ai téléchargé la version d'essais ensuite dans un second temps et après avoir lu les renseignements techniques j'ai décidé d'acheter cet accordeur, pour une première un jour a suffit en respectant à la lettre toutes la procédure décrite dans le manuel d'utilisation livré en ligne gratuitement. Je ne puis que recommander fermement ce produit. Bien cordialement à tout lecteur de ce message de satisfaction. Michel IGNACE

Comment: Ich habe meinen Boston Flügel (GP-178 II) kürzlich das erste Mal mit einem "normalen" chromatischen Stimmgerät ausgehend von einer Stimmung auf 444 Hz unisono gestimmt. Als Amateur war das Ergebnis (wie soll's auch anders sein) nicht sonderlich gut. Ich befürchtete schon, nicht daran vorbei zu kommen, wieder einen erfahrenen Klavierstimmer zu bestellen. Dann stieß ich auf Dirk' Piano Tuner und habe nach Anleitung zunächst sämtliche Töne aufgezeichnet, um die optimale Streckung vom Programm berechnen zu lasse. Anschließend habe ich Ton für Ton, Saite für Saite mit der best möglichen Präzision gestimmt. Das Ergebnis war umwerfend !!!! Der Flügel klang noch nie so rein und brillant - einfach so wie man es sich von einem Flügel (im Konzertsaal) vorstellt. Ich kann nur jedem empfehlen, diese Software zu kaufen! Das Programm ist wirklich jeden Euro und Cent wert. Mit ein wenig Fingerspitzengefühl wird hier auch der Amateuer zu einem sehr guten Ergebnis kommen. Vielen Dank Dirk! Einfach weiter so - ich freue mich schon darauf, Neues von zu hören... Freundliche Grüße / best regards Philipp
