The Korg TM-1 combines a precise tuner and versatile metronome in the smallest and lightest model in the TM Series. Monitor pitch and rhythm simultaneously, with a wide C1–C8 tuning range, 30–252 BPM metronome, 15 rhythm and beat variations, and a compact 51g design that's ideal for practice anywhere.

Practice pitch and rhythm together.

Use the tuner and metronome simultaneously to work on two fundamentals at once. The display provides instant visual feedback on your tuning as the metronome keeps the beat, helping you develop more consistent pitch and timing during everyday practice.

The smallest and lightest TM yet.

Weighing just 51 g without batteries, the TM-1 fits easily into a bag or instrument case for practice on the go. A built-in foldable stand keeps the display visible on a music stand, desk, or other practice surface.

Accurate tuning across a wide range.

A C1 - C8 detection range with measurement precision within ±1 cent supports accurate tuning across a broad range of wind and string instruments. Adjust the reference pitch from A4 = 438 - 450 Hz in 1 Hz steps, or use Sound Out to hear reference tones across one octave from C4 to C5.

Keep the beat in sight.

The metronome uses moving dots across the display to make the beat easy to follow at a glance. Set tempos from 30–252 BPM in single-step increments or use Tap Tempo to quickly match the pace you need. Fifteen rhythm and beat variations provide flexible options for developing timing across different exercises and musical styles.

Tune clearly in noisy environments.

Connect the optional CM-400 contact microphone through the TM-1's 3.5 mm input to send your instrument's vibrations directly to the tuner. This provides reliable pitch detection when surrounding sound makes tuning with the built-in microphone more difficult.

Choose black or white.

The TM-1 is available in black or white, giving you two simple options to match your instrument setup or personal style.
