TM-1
COMBO TUNER METRONOME

Pitch and rhythm. One compact practice tool.

The TM-1 combines a tuner and metronome in the smallest and lightest model in KORG's TM Series. Monitor pitch and rhythm at the same time with an intuitive design that's easy to bring to lessons, rehearsals, or wherever you practice.

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.*

*When using the tuner and metronome simultaneously, triplets, triplet shuffle, sixteenth notes, and sixteenth-note shuffle cannot be selected.

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.
