GarageBand is a fully equipped music creation studio right inside your Mac — with a complete sound library that includes instruments, presets for guitar and voice, and a selection of session drummers and percussionists. With an intuitive, modern design, it’s easy to learn, play, record, create, and share your hits worldwide. There’s a lot of trial and error involved, but here are a few handy tips to make the whole process a lot easier.

• Start a new project: File > New
  • Software Istrument MIDI - Musical Instrument Digital Interface
  • Audio
  • Dummer
    

• Work with Tracks
  • Cycle (range)
  • Change tempo and Time signature

• Windows > Musical typing
  
  
• Loop / Stretch
  
  
• Add tracks: Track > New Track
  • Track: The horizontal rows in the Tracks area are called tracks. Tracks help you organize and control the sound of the recordings, loops, and other material in a project. You record your performances on tracks, and arrange the regions representing the recordings, loops, and other material in a project on tracks.
    
    
    
• Draw: Command key.

• View > Show Editor (E), GarageBand features a set of editors, including the Audio Editor, Piano Roll Editor, Score Editor, and Drummer Editor.
  
  
  • Audio Editor: The Audio Editor displays the audio waveform of the regions on an audio track. You can copy, paste, move, trim, split, and join audio regions. Using the Audio Editor grid, you can precisely align edits with specific points in time.
    
    
  • Piano Roll Editor: The Piano Roll Editor shows notes in MIDI (Musical Instrument Digital Interface) regions as rectangles on a time grid. The position of each note shows the time position where it starts playing, its duration (length), and pitch. You can edit individual notes by moving them, resizing them, dragging them vertically to change their pitch, and in a variety of other ways.
    
    
  • Score Editor: The Score Editor displays MIDI regions as music notation, including notes, rests, and sustain pedal markings. You can add and edit notes and other musical symbols.
    
    
  • Drummer Editor: If you add a Drummer track to a project, you can view and edit Drummer track and region parameters in the Drummer Editor.
