I don't understand the symbols of the graded collection of percussion music in Shanghai Conservatory of Music. Ask the master to point out the drums of the jazz drum kit.

Black is a small military-purchased drumstick, and hollow is a timpani drumstick. All three movements have traces of drum brush.

The hollow frame is the lower snare drum drum string, and the diagonal is the upper drum string. . . .

The last empty drum of the sixteenth note in the first picture is the drum edge, which should ring immediately on the basis of the drum.

The second picture shows a small snare drum drumstick in the right hand and a timpani drumstick in the left hand.

If all the notes in the music are hollow squares, it is a drum, and the cross is just a drum.

Hey. . . Your teacher won't tell you. . . This song is still my exam. . . .
