Well, I have found that the most effective therapy for uninspired days of practice room boredom is quite easy to take and very effective. I'm recommending massive doses of this medication with no limits on refills! Oh, there are side effects, but I don't think you'll find them to be a problem. In fact, I think you'll find them euphorically addictive. Simply inject generous portions into each ear several times a day, and I doubt you'll be needing a followup appointment.
Label instructions: Apply liberal amounts of your FAVORITE BRASS RECORDINGS. Inject into both ears. Repeat at least 3 times daily.
WARNING: Failure to take this medication consistently may cause boredom, drowsiness, depression, and in some cases suicide. Musical Alzheimer's has been shown to be the result of listening only to oneself for long periods of time.
High quality brass playing is infectious. Don't leave home without it.
