Korg TM-1 Combo Tuner & Metronome (Black)

The Korg TM-1 is a dual-function device that combines chromatic tuning and a rhythm guide in a palm-sized housing weighing just 51 grams without batteries. It addresses a common practice-room need: running both tools at once without switching modes or carrying separate units. The tuner offers C1 to C8 detection range with ±1 cent accuracy, while the metronome spans 30 to 252 BPM with tap tempo and multiple subdivisions including triplets and sixteenth-note shuffle patterns.

Calibration adjusts reference pitch across A4 = 438, 450 Hz in 1 Hz steps, accommodating ensemble work and historical temperaments. A 3.5 mm input accepts the optional CM-400 contact microphone for cleaner tracking in loud environments. The foldable stand props the display at readable angles on music stands or desks. Auto power-off prevents battery drain, with runtime reaching approximately 400 hours in tuner-only mode and 200 hours with metronome engaged.

The beat engine supports 0, 9 beats per bar alongside straight eighth notes, triplet and shuffle variations, addressing asymmetric metres and swing feels common in jazz and contemporary music. Its 21 mm dynamic speaker provides audible click tracking without headphones. The compact footprint slips into wind and string instrument cases without adding bulk, making it a practical grab-and-go option for rehearsals, lessons, and backstage tuning between sets.
