Chord Formation

A chord is nothing more than the union of 3 or more different notes played at the same time. If it’s a union of 3 notes, we call it a triad. If we press 3 different keys of a piano (different meaning that they are not the same note, not even in a different octave), we will have a chord, we won’t know what his name is, but it is a chord. Depending on how we form the triad (specifically, the interval or number of semitones there is between the notes forming the triad, we will have one type of chord or another. Usually, and this applies to all chords, we will have a “base” note, which we’ll call “tonic”, from which the chord will be named after, and from which semitone distances will be calculated to the other notes of the triad, in order to define the type of[…]

Before we move on, let me introduce the notion of scale. A scale is a set of different notes that have a certain relation together. Depending on that relation, we will define the name of the scale. The first note is called tonic or root. The rest of the notes, called intervals or degrees are assigned by order: second, third, fourth, fifth, sixth, seventh (we could have the eight, which is the same note as the tonic, just an octave higher). Normally, intervals are written in Roman numbers, for example if we see V it refers to the fifth degree, which for instance among the C scale, is G. A major scale is a succession of 7 notes, one tone away from one another, except between the third and fourth degree, and between the seventh and eighth (exactly the same note as the tonic) which are separated by a semitone.[…]
