Here are ten ways Band in a Box can help with learning an instrument
1) Band in a Box (BiaB) can lay down a drum track for you to play along. Select a style, set the tempo, mute all instruments except drums and hit PLAY. You can choose to loop the track or, if you don't like the stopping and starting, loop a section.
2) BiaB can lay down a drum track AND other instruments for you to play along. Type a chord progression into the chordsheet, select a style, set the tempo and hit PLAY. Mute the instrument you are playing. As above you can choose to loop the track or loop a section.
3) Load a popular song from thousands on the internet, play along. Read the chords, notation or tab from the screen as you play.
4) Interpert a midi file from tens of thousands on the internet and play along. Read the chords, notation or tab from the screen as you play.
5) Have BiaB create an original composition for you on the fly. Just pick a style and BiaB will do the rest. This is challenging since you will never have heard the song before.
6) Slow the tempo until you have your part figured out.
7) Transpose any song to any key with just a click.
8) Change the style of a song. If you are tired of playing 'Proud Mary' like CCR, then try it as a reggae tune. This is fun and good practice.
9) Record your instrument as you are playing along. This is excellent for checking how well you are playing without the accompaniment.
10) Watch the guitar/bass window or the piano window or drum kit to see how BiaB is playing in a given style. This is useful if you don't have any idea how to start or what would sound good. The fingering patterns are sometimes crazy but it's a good place to start.
