Have you ever noticed how songs like "Amazing Grace" or "Swing Low, Sweet Chariot" feel so catchy and easy to sing?
They use a pentatonic scale, a musical ladder made of just five core tones with no awkward clashes.
The word pentatonic comes from the Greek word pente meaning five, and tonos meaning tone.
A standard pentatonic scale uses the solfège syllables do, re, mi, so, and la, completely skipping the half-step notes fa and ti.
What happens when a melody needs to dip lower than "do" or climb higher than "la"?

Stretching the Scale

An extended pentatonic scale takes those same five tones and repeats them lower and higher.
Below do, we add low la (written as la,la,) and low so (written as so,so,).
Above la, we reach up to high do (written as do′do'), giving your voice a full playground of notes to explore.
Now that we know the syllables in order, how do we spot them on the five lines of a music staff?
