This article discusses how MIDI and other computer technologies can help students build their musical skills in the classroom and at home. MIDI (Musical Instrument Digital Interface) has provided music teachers with increasing opportunity to use quality computer-developed musical accompaniments in teaching music to children. Standard MIDI files are available on diskettes and CDs that are included with music texts and method books, allowing accompaniment for singing, playing, and movement activities. Lessons in these books employ MIDI files to facilitate student growth in creativity; knowledge of theory, timbral awareness, and music-analysis skills. Many teachers are now placing MIDI files and home music-learning lessons on the Web so students can work on and practice assignments at home. This article looks at the use of MIDI accompaniments and provides some suggestions and models for incorporating these resources into music teaching. Included are follow-up activities, a list of MENC resources, and 3 notes.
