Harmonic Musical Intervals
In music, there are 12 semi-tonal notes to make up a complete octave. Semi-tonal means that the notes are consistent in their tuning and perfect in pitch with each other, instead of micro-tonal intervals, which are much closer and smaller than the 12-note scale.
With each change in interval, the harmony of the 2 notes produces a new mood or mode, that can be very powerful in captivating one’s mood.
