How to play?
The trumpet is a musical instrument with a high register in the brass family.
There are several types of trumpet, but the most common is a transposing instrument pitched in B with a tubing length of about 148 cm.
If you are new to music, you may want to start with something simple, like the rhythm game. You can also play by yourself, by choosing the mode “solo” or “duet”.
The game has a learning mode, so you can practice your musical skills by yourself. The learning mode is useful because it helps you to understand the notes you play.
