Or any recording of yourself for that matter. Often we hate to hear ourselves as we can be our biggest critic. Do it anyway! You’ll never learn more about your playing then this way. For every negative: “Why did I play that?” or “A shoot I rushed that fill?” find one positive in your playing: “Hey that was tasty” or “The tempo stayed nicely” Just use your smartphone to record yourself at the gig at the coffee shop or restaurant. What may be a mundane gig can now be a great opportunity to fine tune those common grooves and check on your time consistency.
