Abstract
An electromagnetic scanning metronome comprises a laser to produce a beam of light, and comprises a surface to reflect the beam of light to produce a visible line of light which extends over an image of sheet music. The metronome includes apparatus to move the laser and visible line of light from left to right with respect to the image of sheet music.
Claims4
In combination with an image of sheet music, an electromagnetic scanning metronome comprising
- (a) at least one laser producing a beam of light,
- (b) a stationary surface
- (i) canted with respect to said beam of light,
- (ii) including parallel striations perpendicular to said beam,
- (iii) reflecting said beam of light to produce a swath (20) of light forming a vertically oriented, elongate, visible line of light (17) on and moving across said image of sheet music, and
- (c) apparatus to move simultaneously said laser and visible line of light from left to right with respect to said image of sheet music.

In combination with an image of sheet music, an electromagnetic scanning metronome comprising
- (a) a plurality of lasers (15) each producing a beam of light,
- (b) a stationary surface
- (i) canted with respect to said beams of light produced by said lasers, and
- (ii) reflecting periodically each of said beams of light to produce a swath (20) of light forming a vertically oriented, elongate, visible line of light (17) on and moving across said image of sheet music, and
- (c) apparatus to move simultaneously each of said lasers
- (i) 1st from left to right to reflect said beam of light produced by said laser off said stationary surface to form a vertically oriented visible line of light on and moving across said image of said sheet music, and
- (ii) 2nd from right to left such that said beam of light produced by said laser is prevented from reflecting off said stationary surface to produce a visible vertically oriented visible line of light on and moving across said image of said sheet music.
