Amazing Grace

The most-loved hymn in the English language — and a perfect first fingerstyle melody, because the whole tune uses just five notes.

Traditional hymn (John Newton)Folk & Country· Key: G majorPublic domain
How to find the key: G major — the entire melody is the G major pentatonic scale (G, A, B, D, E), resting on G at every cadence. No half steps anywhere, which is why it's nearly impossible to sing wrong.

Why it works

A waltz-time (3/4) hymn: one chord per bar, melody in pure major pentatonic — the same five-note pool behind countless folk and gospel tunes.

The climb to the long high D (“meee…”) is the emotional peak — held over the V chord, then the tune walks back down to rest on G.

Traditional performances ornament the tune with little triplets — three notes squeezed lazily into one beat.

Structure

Public domain: the interactive lesson carries the full melody note-for-note — including the traditional triplet ornaments and the tied note — transcribed from the traditional setting, with an A–B loop for phrase practice.
