This storage capability allows you retrieve the data and play back the song at a later time without having to re-record the music. A sequencer, therefore, is a device that can record, edit, store, and play back digital data that represent a musical performance. Teachers can use a sequencer to create minus-one accompaniments for any song in a variety of musical styles. Sequencers offer the ability to play a song back in any key and at any tempo. This means that song keys and tempos can be optimized to meet the needs of all students.
Teachers can learn the basics of sequencing and create their own songs and arrangements.
In addition, pre-recorded songs for sequencer playback can be purchased from publishers such as Alfred, Hal Leonard and Warner Brothers. Other sequencer song files can be found on the Internet and downloaded into the sequencer. For elementary and middle school students, sequencers make it possible for the teacher to provide a variety of accompaniment styles for classroom instruments such as recorders, Orff instruments, guitars, and keyboards. A sequencer accompaniment allows the teacher to circulate within the classroom and to join in the musical performance. A sequencer has the capabilities of a tape recorder, a sound mixer, and word processor in addition to other unique capabilities.
