Students continue to build their repertoire of basic melodies and folk tunes. They develop notation systems that demonstrate variance in pitch and rhythm. Activities reinforce the identification and production of note values and in-score symbols. Using systems of number and/or letter notation, students execute basic rhythms both vocally and instrumentally. Listening to various styles and forms of music with greater discrimination creates an appreciation of composition. Through instrumental and vocal work, students learn aspects of ensemble playing. They continue to explore the instrument families of the orchestra through hands-on lessons while reviewing the identification of orchestral and band instruments.
