Practicing with a sequenced accompaniment Students at all levels can benefit from practicing with a recorded sequence. They can practice playing with a steady beat. They also can learn to adjust the tempo for practice. Some teachers use the sequencer to challenge students by providing accompaniments of difficult literature. Exercises can also be created to help students reinforce basic skills.
Some conductors use the sequencer as a performance tool.
This is especially effective for choirs and instrumental ensembles. Suppose you had a piece that called for additional instruments or you wanted to provide a fully orchestrated accompaniment. One option is to record a sequence and use the MIDI sequencer in live performance. Use the sequencer in live performance Joe Brennan, the orchestra director at Haverford High School, has used the sequencer in performance. I recall one occasion when there was a group of excellent violin students but no one to play the cello part.
