What to practice

Sometimes I go for periods of time without playing and then when I do play it will be for hours. I think it is better to stay consistent and practice each day. In this way you build upon lessons and your strength and technique improve incrementally. I think a great thing to practice is to record comping some chord progressions and then playing and soloing over them. You can also use backtracks to play over from software. Purchase a Jazz fake or real book and learn to play over these progressions. Learn the melody and break down the chord progressions into scales and modes. Learn to play around the melody and use phrasing and licks.
