Check out these backing tracks for you to jam along. backing tracks are built to improvise your instrument with it. they are like support tracks to whatever you play, or you can do just plain practice (Scales, Chords, Arpeggios) while staying in a particular key. Practicing with backing tracks will help you to get deeper understanding of your instrument, jam in every octave, every possible scale shape, start with any scale degree and find new techniques and discover new melodies, i’ll be glad if you share your improvisation track here.
Happy Improvisation 🙂
