The drop-down menu for the block.

The Play Drum () for () Beats block is a Sound block and a Stack block. The block will play the specified instrument for the specified amount of seconds using a MIDI drumset. Even though the block uses the word "drum", the choices in the drop-down menu are many different percussion instruments including drums, triangle, bongos, cowbell, vibraslap, and various idiophones.

This block used to be called Play Drum () for () Secs, but was changed because the length of a beat can now be changed with the Set Tempo by () bpm block.

Entering a negative value, 0, or any value above 18 for the drum will use the "(3) Side Stick" drum.

Example Uses

As the block plays an instrument, it is widely used when a song is played with the Sound blocks.

Some common uses for the Play Drum () for () Beats block:

  • Easy sound effects (some of the choices in the drop-down menu are sound effects such as a clap)
play drum (8 v) for (0.25) beats
  • Musical projects where you control instruments
when gf clicked
repeat until <<(answer) > [26]> and <(answer) < [88]>>
ask [Drum?] and wait
if <<loudness?> > [10]> then
play drum (answer) for (0.1) beats
  • Creating a song made by blocks
play drum (48 v) for (0.2) beats
play note (60 v) for (0.6) beats
play drum (47 v) for (0.2) beats

Rhythm Notation

Unlike sheet music, the block uses numbers to notate rhythm. This table could help when taking a rhythm from music. It shows the beats number values for the most common rhythms in the most common time signatures, interpreted in the most basic ways.

play drum (10) for (10) beats :: obsolete

In the switch from Scratch 1.4 to Scratch 2.0, some of the drums were not available in flash/browsers. To deal with that, there are two versions of the drum block. The obsolete one is the one that was used in Scratch 1.4 projects.
