Join other serious music students from all over the world for a summer semester in Boston. In just 12 weeks, you will complete the first semester of Berklee's regular college-level core curriculum. The Full-Credit Summer Program offers you the opportunity to explore Berklee on a summer-only basis. Normally, you must be a full-time student seeking a degree or diploma in order to earn a full semester of credits.
For admission you must be at least 16 years old by the start of the program. You'll also need a minimum of two years of formal music training or experience on your principal instrument or voice, and good working knowledge/familiarity with the written fundamentals of music theory (including rhythmic notation, melodic notation in treble and bass clefs, key signatures, major and minor scales, intervals, and construction of triads and seventh chords). Because you'll be enrolled in classes with full-time students, it's important that your musical abilities and written theory and ear training skills are at a compatible level.
