RELAXATION JAZZ STANDARD MUSIC BOX (癒しのジャズスタンダードオルゴール20)

Music box (as a genre tag) denotes pieces written for, recorded from, or emulating the bell‑like plucked‑steel timbre of mechanical music boxes. The sound is produced by pins on a rotating cylinder or disc plucking tuned teeth (a steel comb), yielding a delicate, chiming decay that evokes lullabies, nursery tunes, or uncanny clockwork. Historically the instrument emerged at the end of the 18th century and flourished through the 19th, before phonographs displaced it. In contemporary usage, “music box” refers not only to antique instruments but also to modern sample libraries and synthesizers that imitate the timbre for film, game, ambient, and lullaby contexts.
