How many tones does a standard Western tuning system have in an octave?

  • Twelve

  • Ten

  • Fourteen

  • Eight

Answer

A standard Western tuning system uses twelve tones to an octave. This system is called equal temperament, and it was developed in the 16th century by Vincenzo Galilei. Equal temperament divides the octave into twelve equal semitones, which means that each semitone is the same distance apart. This system makes it possible to play in any key, because the intervals between notes are always the same.
