![]() In other words, it creates a custom tuning for your piano with the best compromise between intervals like fifths, fourths, octaves, and twelfths, the way aural piano tuners do when fine-tuning. Unlike regular chromatic tuning apps that simply tune to a pre-calculated equal temperament, this app actively measures the tonal characteristics of each note and automatically calculates the ideal “stretch” or offset from equal temperament. To tune the entire piano you will need to buy an upgrade through an in-app purchase. The "free" version of this app is primarily for evaluation, and it only allows you to tune notes on the piano between C3 and C5. Dr.PianoMeter is a piano tuning app that will transform your device into a professional quality electronic tuning aid. ![]() And the physicists have gone even further: "Committed piano technicians are volunteering to translate the tuner software into other languages, even into Chinese." While some experts think that working with the new software takes too long, others are impressed by the good result.Īccording to Hinrichsen, demand for the software is surprisingly high: To date the Android version of the software has been installed more than 5,000 times worldwide. "Our Entropy Piano Tuner goes down well especially with piano tuners and it is discussed in specialist forums," Hinrichsen is pleased to tell. Hinrichsen and Wick rectified this problem by using the physical quantity of entropy and a suitable algorithm. Reception of the "Entropy Piano Tuner" with experts The latter, however, are crucial as to whether we perceive a sound as harmonic or not. This is because these electronic gadgets tune the fundamental but not the overtones. So piano tuners need a fine ear and technical skill to harmonise this huge variety of overtones.Įven though simple electronic devices, which allow adjusting musical instruments to the correct tone frequencies, have been around for some time, they are not suitable for pianos, because: "When using these devices to tune pianos, they seem out of tune to the trained ear," Hinrichsen explains. Pianos have a complex range of overtones. What makes the new tuner software special Available for free download, the software is easy to operate and runs on all standard devices, even on smartphones and tablet computers," Hinrichsen says. "So, we published the software under the name 'Entropy Piano Tuner' as an open source project. Lehmann from the Würzburg University of Music." There was, however, a catch to it: At the time, it had only been an idea and no real piano had actually been tuned using this "new method".īut now in October 2015, Hinrichsen announces the implementation of his idea: "Christoph Wick, my former master student, and I developed a software and tested it in a double-blind study in cooperation with Professor Andreas C. Professor of physics Haye Hinrichsen had claimed in a publication that the physical quantity of entropy, which is a measure of a system's disorder, should be useful for tuning a piano. "Piano tuners facing unemployment": That was the media headline a few years ago after some had gotten wind of the new idea from Würzburg.
