-- How to read? --
You see aqua wave and 49 color balls floating on. Those balls are floating up and down as they are given power. You can consider the hight as volume, the ball as pitch(half tone), and the waving as rhythm.
This is designed so that you can imagine breathing(wave) gives power and keeps control of pitch and volume(color ball). So this is the best for wind instrument and vocal trainings.
* You can find technical details at our support site.
-- Pitch estimation and its range --
The aqua wave is used to estimate correct fundamental frequency, which is the most significant pitch. And it is shown lower left. The range of the frequency is from C2 to B7.
While each of 49 color balls represents half tone respectively from A2 to A6, from right to left. The center line is A4.
Musical tuning is done by equal temperament, A440.
