Focus and clarity in the low register are two important basic elements of trumpet playing. These Low Note Exercises and Etudes have been written in order to promote the consistency and effectiveness of daily practice. Mark recommends that you practice one or two each day and rotate through the entire set. Low note etudes are a great opportunity to rest your chops during a taxing practice session as well. They can help to regenerate the lips and re-focus your embouchure during long practice sessions.
