I usually focus on each mode for about 2 weeks. I take about 20 minutes and practice playing to 1st, 3rd, and 5th notes of the mode, then I usually improvise over a chord progresson or vamp that I loop or I play over a backing track. I play in a different key every day, so like A one day B the next, you get the idea. How efficient is this to practice improvising with modes? Should I be doing anything different?
