The most basic chords, built using the 1st, 3rd, and 5th notes of a scale.
When you play three or more notes at once, you create a chord.
Notes are named A, B, C, D, E, F, and G. Half Steps & Whole Steps:
A (Whole tone) consists of two half steps (e.g., C to D).
Sound "happy" or "bright." The formula is: W–W–H–W–W–W–H (Whole, Whole, Half...).
Sharps raise a note by a half step; flats lower it by a half step. 2. Keys and Scales
