I want to share something I think is really valuable; two chord backing tracks for practice. I’m attaching some noodling in C major. I used a 3 note per string scale shape and some double stop patterns to improvise, no charge for the timing and note choice mistakes. I found it helpful to find which notes I could rest on and which I had to move off. It is also simple enough to allow you to use your ear to seek out a next note. It could be more interesting if I went on to some higher register scale positions. The same track could be used to practice triad chord voices of the two chords. The next level would be to try to use chord tones of each chord out of their arpeggio shapes, this is really interesting in something more distinctive and out of key, like a i-V7 track. I won’t post here but if anyone is interested, I have found a nice group of two chord tracks on YouTube, just PM me.
