MusiShuZ

HOW TO USE
Put on the MusiShuZ shoes (a.k.a. MUSIES). Download the MusiShuZ app and start it on your iPhone or iPad. iOS/iPadOS version 13.5 or higher is required. Turn on the Bluetooth light sensors (mice) on your MusiShuZ shoes and go to the settings of your device to pair the mice. Start the app and read the instructions to complete the settings. Start walking or dancing and listen to the notes generated by your feet.
FUNCTIONALITY
You can select any of the dozens built-in MIDI instruments (e.g. piano, cello, piccolo, violin and many more). There are two modes of operation: BEGINNER (play only the 8 white keys in an octave) and ADVANCED (plays all 12 black and white keys in an octave). You can switch to any of the 7 octaves in a full size 88 keys keyboard by clicking the left and right buttons of the Remote Controller, which is included in the MusiShuZ shoes package.
PRINCIPLES OF OPERATION
Imagine that your feet are your hands. Play the MusiShuZ by sliding each shoe as if it is a computer mouse. Slide it to one of the four corners of an imaginary computer or iPhone screen. When you press on the heel of a foot a note is going to play. The notes playable by the left foot in the Beginner's mode are Do, Mi, Sol, Ti (C, E, G, B) and the notes playable by the right foot are Re, Fa, La, Dh (D, F, A, C). The mapping of notes to screen corners (quadrants) is described in the instructions of the MusiShuZ app. The duration of each note is controlled by the amount of time you are pressing on each shoe heel. You can also control the loudness (sound volume) of each note by the distance from the screen center that you slide your feet before you press on the foot heel. Dozens of practice melodies from 18 of language regions are also featured in both sheet and chart music notations.
