Select the region, move the playhead to the position where you'd like to split, and press Cmd-T, or choose Edit > Split.


You can join any recorded regions together, or join loop regions that come from the same original loop.

Tempo, Time (time signature), and Key.


The default time signature is 4/4 (four beats per measure), project key is C, and tempo is 120.


You can change a project tempo by clicking the Tempo portion of the time display and adjusting the Tempo slider.


A single-take Software Instrument recording starts when the first note event is pressed during recording, and ends when you stop recording.


Multipass recordings use a cycle region to determine the length of the recording.

Connect a MIDI or USB keyboard to the computer


Record a Software Instrument keyboard part


Work with Musical Typing


Edit a note in a Software Instrument region

Now that you know the basics of working with Software Instruments, it's time to move on to more advanced recording and arranging techniques. In this lesson, you'll record an additional Software Instrument track using the Musical Typing feature and edit it in the editor. Along the way, you'll learn some new keyboard shortcuts, recording tricks, and advanced music arrangement techniques to double parts, mix instruments, offset regions, transpose key, and fatten the melody tracks as you build the intro score for a podcast or radio show from the rhythm tracks up.

Previewing the Finished Song

Let's take a sneak preview of the finished song, so that you'll have an idea what you're going to build. I've called this song SpaceBass, because the inspiration came from the combination of several strong bass loops with a spacey keyboard part. This is the sort of thing I would score for the intro music to a cool podcast show.


Choose File > Open to open an existing song file.


Select GarageBand 3 Lessons > Lesson_04 > 4-4 SpaceBass final.


Double-click 4-4 SpaceBass final to open the song.

The song opens in the GarageBand window.


Press the Home key to move the playhead to the beginning of the song.

Before you play the song, it's a good idea to turn off the metronome if it is on.

You've successfully worked with the metronome turned on while recording and have probably noticed that it is still on during playback. That might get a little annoying after a while. You have two choices to turn off the metronome during playback. You could go back to the General Preferences window and change the metronome settings to "During recording" only. Or you can go to the Control menu and toggle off the metronome. The shortcut to toggle the metronome on and off is Cmd-U.


Choose Control > Metronome, or press Cmd-U, to turn off the metronome if it is turned on.


Play the project.

There you have it. Let's get started.
