To set the tempo for your song:

1. In the New Project dialog box, drag the Tempo slider left to slow down the tempo,

or right to speed up the tempo. If you need to, you can change the tempo later in

the Track Info > Master Track window.

Music Theory Tip - About the Time Signature:

Each song also has a time signature, which controls the relationship between beats and

measures. A song's time signature consists of two numbers separated by a forward slash, which

look similar to a fraction. The number on the left refers to the number of beats in each

measure, and the number on the right refers to the beat value (the length of the note that gets

one beat). You can use any of the following time signatures in a GarageBand song: 2/2, 2/4,

3/4, 4/4, 5/4, 7/4, 6/8, 7/8, 9/8, or 12/8. The default is 4/4, the most commonly used time

signature.

To set the time signature:

In the New Song dialog, choose a time signature from the Time pop-up menu. If you need to,

you can change the time signature later in the Track Info > Master Track window.

Music Theory Tip – About the Key

Each song has a key, which defines the central note to which the other notes in the music

relate. You can set the song to use any musical key. (Note: Obviously, the Apple programmers

don’t know that much about music theory and key signatures since they have offered such key

choices as D#, instead of Eb. The note of D# exists but the key of D# does NOT! They also

have only offered the key of C# but not Db, which both exist in the real musical world! I guess

it is time to give Apple programmers a lesson on key signatures and enharmonic equivalents.)

To set the key:

1. In the New Song dialog, choose a key from the Key pop-up menu. If you change the

key of a song after recording instruments or adding loops, all Software Instrument

recordings and loops are transposed to the new key. Real Instrument recordings are

not transposed.

2. If you need to, you can change the key later in the Track Info > Master Track

window.

3. Note: If you are using Apple Loops to create your song, the loop will automatically

be transposed as you drag it into the main GarageBand window according to the key

you selected when setting up your composition. If you are going to use Real

Instruments for your composition, you should set the appropriate key here before

you begin recording.
