→Intro to Chords
Let's talk about chords. A '''chord''' is three or more notes simultaneously. One of the notes is called the '''root note'''. Other notes are classified in terms of the intervals they create with the root note (ie their distance from the root note).
'''Triads''' are chords composed of a root note and its third and fifth - these are the most common type of chords. There are 4 main types of triads, depending on the which third and fifth intervals are used:

* '''C''' D '''E''' F '''G'''
This is helpful to quickly get the notes for a particular chord in the key of C Major. As we learn more about other keys and get more accustomed to the intervalic relationship between each pair of notes in the chromatic scale, we will be able to derive the member notes for any particular chord quickly.
''Building chords by stacking third intervals as described above is called '''tertian harmony''' - alternate harmonic structures exist and are covered later in [[Quartal Harmony|advanced lessons]].''
