If you want to make progress quickly when practicing your instrument or learning to sing new pieces, a practice log and journal is crucial.
Studies have shown that any activity that you track will result in a higher favorable return on your time invested. This is because you are creating a system of self accountability which propels you forward in your growth.
The same is true of practicing music. This can be very easily accomplished with a practice log. A practice log is a sheet of paper that contains a place to track your practice sessions including the time, date and a tally of how many times or how much time you have spent practicing this month, or week.
