Tired of guitarists taking all the lead! Bass can solo over some blues and sound good too. Here is a backing track I made. All you have to know for lead here is feel it, and play notes in D major.
If you want you can download an app called Spire. It will give you the option to open in Spire (link below). You can actually add your own track and play right to it and record a track right from your phone mic. Just use headphones for monitoring so it doesn’t record the backing track too. Be fun to hear what you all come up with!
