How do I set the tempo of the song?
The tempo is the speed of the song, commonly expressed as the number of beats per minute, or BPM. You can change the overall tempo for the entire song at any time. That can be done from the speed change button in the bottom left part of the screen.
You can also make changes after you save the song. To do that, go to the Edit menu of the song, then click on Edit timing.
Wait, what is a beat?
A beat is a "pulse" in music. In most popular music, beats are usually organized into groups of three or four, which is what Composer currently supports.
What are tags for and how do I use them?
