Play the Bass in GarageBand for iPad
Using the Bass, you can play notes and bass lines. You can choose from different acoustic and electric bass sounds.
Choose the sound of the Bass
Tap the bass icon in the upper-left corner, then tap the sound you want to play. You can also swipe left or right to change to the previous or next sound.
Play notes of a chord
Tap the strings on the fretboard in one of the chord strips. Each string plays a different note of the chord.
You can add your own custom chords to play.
Play a bass line
Turn the Autoplay knob to one of the numbered positions.
Tap a chord strip. Tapping a different chord strip plays the same pattern with the notes of that chord, and tapping with two or three fingers plays variations of the bass line.
Tap the chord strip again to stop the pattern.
Play individual notes
Tap the Chords/Notes switch on the right to switch to Notes view.
Tap the strings on the fretboard at the fret for the note you want to play. You can also bend strings vertically to bend the pitch of a note.
To play notes of a particular scale, tap the Scale button, then tap the scale you want to play.
The fretboard changes to show note bars rather than frets. Tap the bars to play the notes of the scale.
