Please add as daily or weekly more gamification options.
I can suggest for piano the following;
Out of 10 tries, the user will find the note, chord and even a scale on what is requested on the screen. The faster the user plays the requested note or chord the better the score will be. Example; let’s say on the screen on my first try is requested to play chord Dm . The score will be counted based on accuracy/ time spent to play the chord. If the user plays correctly or fails to play the chord, the game continue to the second try until has all 10 tries done. The 10 times tries scores will be counted based on accuracy / time on each try. Also it can be added a filter of scales that user can choose to play the game or randomly.
This game will make user being more familiar with chords and also by repeating them in a fun way, will increase the muscle memory for the user.
