Rune sequence puzzle

Four standing stones hum a tune, one note at a time. Sing it back.
Four moss-crusted standing stones ring a shallow hollow. When anyone steps into the circle the runes carved into them begin to glow and hum, one after another. The circle answers anyone who repeats the song, a note longer each time, until the whole tune has been sung.
The runes flare green, and the first stone begins to hum.
