Korg KDM-3 Metronome, Black

A versatile digital metronome with powerful sound, flexible rhythms, and a classic design

The Korg KDM-3 Digital Metronome combines the familiar appearance of a traditional mechanical metronome with the precision and versatility of modern digital technology. Its tempo range extends from 30 to 252 beats per minute, with a choice of traditional pendulum steps, one-BPM full steps, or tap tempo. Nineteen beat and rhythm patterns provide useful options for focused practice, while eight selectable metronome sounds make it easier to choose a tone that remains clear alongside your instrument.

Beyond basic tempo practice, the KDM-3 includes a Sound Out mode that produces reference pitches from C4 through B4, with adjustable A4 calibration from 410 to 480 Hz. A built-in timer can be set from 1 to 120 minutes for structured practice sessions. The large 36 mm dynamic speaker delivers a clearly audible beat, while the 3.5 mm headphone jack supports quiet practice. Powered by four AAA batteries, the compact black KDM-3 is well suited to lessons, rehearsals, individual practice, and everyday music study.
