# tempoTrack

The track that contains tempo information about the sequence.

## Declaration

```swift
var tempoTrack: AVMusicTrack { get }
```

## Discussion

Discussion Each sequence has a single tempo track. The framework places all tempo events into this track along with other appropriate events, such as the time signature from a MIDI file. You can edit the tempo track like any other track. The framework ignores nontempo events in the track.
