Play the Smart Drums in GarageBand for iPhone
You can quickly create drum grooves with Smart Drums. Simply drag drums into the grid and position them to set the complexity and intensity of each drum part. After you record a drum groove, you can make changes and preview the changes before re-recording the drum groove.

Add drums to the grid
Drag a drum into the grid.
The further right you place the drum in the grid, the more complex its part; the higher you place it, the louder it plays. You can reposition drums in the grid until you like the part each one plays.
To stop playback, tap the Power button to turn it off. To clear the grid, tap Reset.

You can tap the Dice button multiple times to try out different grooves.
Record a drum groove
After you have created a drum groove, you can record it to use in the song.
Tap the Record button in the control bar.
If you drag drums into the grid, change their position or drag them out of the grid, your changes are recorded as part of the drum groove.
When you finish, tap the Play button in the control bar to stop recording.
Edit the drum groove after you record
After you record a drum groove, the grid shows what has been recorded at the current playhead position. For example, if you recorded a snare drum starting at bar 5, moving the playhead to bar 5 (or later) shows the snare in the grid.
You can edit the recorded drum groove and try out your changes without altering the recording. Playback starts when you add or move drums in the grid so you can hear your edits. To stop playback, tap the Power button to turn it off. To keep your changes, record the groove again.
