There are so many ways to get musically active in the community. Take advantage of them!
Maine Academy of Modern Music or MAMM is an organization that teaches kids how to play music. MAMM offers instrumental and vocal lessons, summer camps, and band groups with an instructor. There are locations in Portland and Bangor. MAMM is a great organization that helps kids connect and improve the musical skills and knowledge.
Midcoast School of Music is similar to MAMM. They offer lessons for drums, piano, guitar, bass, horns, and voice as well as classroom-style classes about music theory and improvisation. Midcoast also offers 8-12 week ensemble groups for students with similar musical interests to connect and play music together.
Keep in mind that any musical opportunity that you can take is beneficial even if that means singing to yourself or attempting to make music alone. Don't feel like you need to join a big group in order to become musically active, anything helps!
