Abstract
Abstract This music teaching device includes a cabinet having two aligned rows of lamp indicators providing coordinated visual representation of an associated aligned sheet of music. The lamps of the first row of indicators are illuminated consecutively, each lamp remaining lit for the same time period to provide a visual metronome. The lamps of the second row of indicators are illuminated in selected groups coordinated with metronome lamps each group remaining lit for the time period corresponding to the notes on the sheet music. The device includes a scanner, which provides triggering pulses producing sustained, rather than flashing illumination of individual lamps and groups of lamps; and a switching system, which ties individual lamps of the second row together for simultaneous indication. In addition to the visual indication this device provides associated audio indication, which is directly related to the visual indication. The audio metronome provides a choice of sounds for accent purposes and the audio note section provides a choice of pitch for both individual notes and chords.
