It is well known that musicians need to practice the same passagens over and over until they get it stable and finally perfectly. However, repetition can be also perverse, since by repeating we tend to lose our focus. It is important to work in detail, but it is also important to review basic technic aspects.
I recommend my students to review those basic aspects right after the warmup, by dedicating 2-3 minutes to each one of the basic technical aspects (legato, staccato, flexibility, low range, high range, lip trills, stopped notes, etc...). This way they are reviewed every single day, without forgetting to practice any of them. There are hourglasses with approximately 3 minutes that are used to teach kids to brush their teeth during the recommended amount of time. By using this accessory during the music practice, big practice sessions can be easily split into smaller 2-3 minutes tasks.
This is one more strategy to include in the music practice techniques arsenal.
