I highly suggest NOT purchasing an instrument online (please do not purchase instruments from Amazon or any grocery store) for a large variety of reasons.
If you are insistent on purchasing an instrument without going through one of the recommended music stores, PLEASE reach out for help! I am MORE than willing to help in any way I can when purchasing instruments to ensure students have access to quality equipment.
Students who are not on an appropriate equipment set-up WILL experience far less success than their peers.
A Trumpet Mouthpiece (should be included in a rental) Vincent Bach 7C
A soft cleaning cloth (polishing cloth) to wipe oil and fingerprints off the instrument's exterior
Valve Oil (Al Cass Fast Valve Oil, Blue Juice)
Slide Grease
Access to a metronome/tuner to have at home (there are also many free apps available for mobile devices)
A folding music stand for practicing at home
