This piano uses set screws with a linear torque response, rather than the conventional tuning pegs, for fine adjustment of string tension. The issue has been addressed in the design of a post-modern piano that is currently being developed by Prof. Due to the unpredictable response of tuning pegs to applied torque, tuning a conventional piano is a mechanically difficult. This tuning is a difficult task which should be performed by an expert piano tuner. Strings exhibit what is known as harmonic stretch, in which the harmonics produced are slightly higher than the expected frequencies (note the mismatch of frequencies between C1 and C2 in the figure below).Īs with any musical instrument, pianos need to be tuned periodically to keep them performing their best. Since each octave in the musical scale represents a doubling in frequency, one would expect that the fundamental frequency of a note would be identical to the 2nd harmonic of a note one octave below. The vibration of the strings is characterized by a fundamental frequency and a number of harmonics. The strings are grouped in sets of two (called a bichord) or three (called a trichord), and within a set each string must vibrate at the same frequencies. To produce sound, the piano converts a pianist's manipulation of its keys and pedals into vibrations of internal piano strings. Pianos have played a significant role in western culture for more than three-hundred years.

Access to all future features and enhancements.

Custom tuning styles: create a custom tuning curve by adjusting interval weighting and stretch.

Pitch raise mode that calculates overpull for an initial first pass “rough” tuning (for pianos that are extremely flat).

Save and load tuning files, so a piano doesn’t need to be re-measured each time it is tuned.

#Professional piano tuner device plus#

Upgrading to Professional unlocks all features of the “Plus” version, plus the following:

Calibrate device to an external frequency source.

Tune to historical or custom temperaments.

Tune to frequency standards other than A=440.

Tuning functionality for the entire piano.

Upgrading to “Plus” adds the following functionality:

Swipe in the graphing area to show a live frequency spectrum or the inharmonicity of measured notes.

Ability to measure each note on the piano to see how its current tuning compares to the ideal tuning curve (see if a piano is roughly in tune).Tuning functionality for the mid-range of the piano only.

The Free version includes the following functionality: The extra functionality is unlocked through one-time in-app purchases. There are three levels of functionality: a free (evaluation) version, a paid “plus” version with basic tuning functionality, and a “professional” version with features geared towards professional piano tuners. 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.
