About this app

For all jazz students.
STUSTA brings a realistic jam session experience to your daily life, using recordings of performances by top professional musicians.
The recordings consist of a rhythm section of piano, bass, and drums, and you can turn off any part while you play.
With all parts turned on, it functions as a quartet for the front line, while turning off the bass or drums functions as a trio with the piano playing the theme or improvisational solo.
In addition, the new "Listen Mode" feature lets you listen to the complete performance by the host trio while viewing the sheet music.
Not only can you select a song from the Listen Mode song list, but you can also switch from a song selected in Practice Mode to the same song in Listen Mode with a single touch.
Now you can feel closer to jazz and learn in any situation, even when you can't practice.
The recording and playback function (beta version) lets you record and play back your own performance on the spot, allowing you to review it objectively.
