How it sounds

The bottom of every major chord. Bright and open; it is the clearest single sign that a chord is major rather than minor.

Songs to remember it by

Hum the start of When the Saints Go Marching In or Kumbaya. The jump between the first two notes is a major third. Reference songs get you started; after a while you will hear the interval itself.

On the guitar

4 frets up on the same string, or on the next higher string, 1 fret back. With the lower note on the low E or A string in standard tuning; shapes that cross from the G string to the B string move up one fret.
