Major Pentatonic Scales on Piano

The major pentatonic scale removes the two half-step-adjacent notes (the 4th and 7th degrees) from the major scale, leaving five notes that blend smoothly over almost any diatonic chord. It is one of the oldest and most universal scales in music — found in folk traditions across every continent, in blues and rock guitar solos, and in countless melodies from nursery rhymes to pop hits.

Formula: W–W–WH–W–WH (whole–whole–whole+half–whole–whole+half)

Intervals: P1–M2–M3–P5–M6–P8

Scale degrees: 1–2–3–5–6

Sound: Open, bright, universally pleasant, folk-like

Also known as: The "safe" scale — no note clashes with the underlying key

Why remove two notes? The 4th and 7th degrees of the major scale form the only half-step intervals. Removing them eliminates all semitone tension, producing a scale where every note sounds consonant against the tonic chord. That is why pentatonic melodies sound instantly singable.
