Unit 2. 2nd ESO. Harmony & Chords

​When we talk about Harmony, we are referring to the accompaniment that a melody has, that is, a set of sounds that are played at the same time, accompanying the melody and enriching it.

​In a musical group, the singer makes the melody and the other instruments (guitar, keyboard and bass) make the harmony, that is, the accompaniment. Finally, the drum set makes the rhythmic accompaniment.

​Unlike the melody, which is a set of notes one after another in a successive sequence, in the harmony we are talking about simultaneous sounds, that is, sounds that are played at the same time. These simultaneous sounds are organised in Chords

​A Chord is a set of three or more notes that are combined and played simultaneously.

​The most common and simple one is the perfect chord: at 3^rd and 5^th intervals over a given note:

​To make a perfect chord from a note we must overlap two musical notes at 3^rd interval
