# Introduction

Musical is a music studio you talk to. Ask for music or a change, and Musical does the work on real tracks. You keep what you like.

## Three views

Every project opens in one of three views. Switch between them at the top, or with `⌘1` `⌘2` `⌘3`.

### Agent

The conversation with Musical, and what it builds beside it as it works: the notes it writes, the parts it reads, the edits it makes.

### Studio

The tracks, to edit by hand. Drag to move a clip, drag its edges to trim, press `S` to split it under the pointer, double-click to open its notes. The inspector on the left shows the selected part's tempo, notes, effects and level.

### Play

The same tracks, full width, each lit as it plays. Musical can show the drums it hears as their own lanes.

## How a request goes

1. **Ask.** Type what you want in the chat. To ask about part of the song, select clips or bars first and choose Ask Musical.
2. **Watch.** Each step shows as it happens, drawn as music: the notes, the parts, the sections.
3. **Review.** The changes wait in Review changes. Switch between Before and After, then keep them all, keep some, or reject them.
4. **Keep going.** Each change you keep is a version. Undo with `⌘Z`, or ask for something else.

## Bring your music

Drop a song, a video or a MIDI file on the studio: MP3, WAV, FLAC, MP4 and MIDI all work. Musical splits a song into parts you can play with, and maps its sections, tempo and key.

## Shortcuts

`Space` plays and pauses. `⌘K` finds any command, or asks Musical. `S` splits. `R` records from your microphone. `⌘Z` undoes.
