Intervals
An interval is the distance between two notes. Every name you'll meet for one is in the chart: the old Latin name of the scale degree, the short name players say ("a minor 3rd", m3), the solfège syllable, the chord numeral and the number against the major scale. Press a column to hear it; a song for each one makes it stick.
