Head to the Practice Window in Band-in-a-Box® and you'll be able to access the "Ear Training Window - Chord Tutor" feature within the program. You can also access this using the keyboard command Ctrl+Shift+J.
The Ear Training tutor is a great way to learn to "play-by-ear" - the program will play a chord, and you'll identify it... it's that easy! (or difficult, depending on how well you know your chords!) Plus, your score can be tracked so that you can record your progress. It's never too late to learn!
Although this video is based on an older version of Band-in-a-Box®, it is still accurate - so check out this feature in action: https://youtu.be/hNkraN1Y-Xs
(or, load the program and give it a try!)
