The listing, Seth Thomas Electronic Metronome has ended.
This item was in a bunch of stuff. It works great, It comes on and makes sounds. I tried to get a picture of the red light but the flash kept throwing it off, so I took one with the flash off so it's kinda dark.Oh it needs to be dusted off too.
Metronomes may be used by musicians when practicing in order to maintain a constant tempo; by adjusting the metronome, facility can be achieved at varying tempi. Even in pieces that do not require a strictly constant tempo (such as in the case of rubato), a metronome "marking" is sometimes given by the composer to give an indication of the general tempo intended, found in the score at the beginning of a piece or movement thereof.
Tempo is most always measured in beats per minute (BPM); metronomes can be set to variable tempi, usually ranging from 40 to 208 BPM; another marking denoting metronome tempi is M.M., or Mälzel's Metronome.
