Music intervals explained It is the music interval that starts on a chromatic scale note and ends on the same letter note at double the frequency.Īlright, let’s skip the physics lessons on pitch frequency and get into one of my favorite subjects: intervals. It is actually 13 notes when you count the first and last notes. The “distance” of an octave spans a total of 12 notes or semitones, the entire chromatic scale. A note at triple the frequency (1760 Hz) would be two octaves higher than concert A. ![]() If a second note is played at double the frequency (880 Hz), then that would be A one octave higher. If you have heard orchestras tuning up in person or on TV, then you are hearing the musicians playing concert A at 440 Hz. You need the term “octave” to explain the chromatic scale, and you need the chromatic scale to understand what intervals are. Intervals, the octave, and the chromatic scale are closely related. The chromatic scale is created by dividing the octave into 12 equal parts called semitones. An octave is a distance from a note at a specific frequency to the next note that is double that frequency.An octave is divided into 12 equal parts (half steps) and those divisions make the 12 notes of the chromatic scale.Octaves span the distance of 12 semitones. ![]()
