Why does the needle wobble?

Slight wobble is normal: vibrato or background noise.

What Is a Chromatic Tuner?

A chromatic tuner detects whatever pitch you play and shows the nearest semitone with the deviation in cents. This is the most flexible kind of tuner: it works for any instrument since it is not pre-configured to specific strings. Guitar players sometimes prefer instrument-specific tuners because they limit detection to expected notes, reducing octave errors. Chromatic tuners trade that for universality.

How to Tune Online With a Chromatic Tuner

Play a note. The tuner identifies the nearest semitone and displays a needle showing how far you are from perfect tuning. Centre needle = in tune. Needle left = flat (raise pitch). Needle right = sharp (lower pitch). The in-tune zone is ±5¢. Most listeners can't hear deviations smaller than this. For ensemble playing or recording, aim for within ±2¢.

Lock-to-Note Mode

Lock mode forces the tuner to compare against a specific note. Use this when tuning a string that is significantly out of pitch: chromatic mode might snap to the wrong semitone. Lock to your target and adjust until the deviation reaches zero.

Common Chromatic Tuning Problems

If the tuner jumps between two adjacent notes, you are exactly between them: adjust pitch decisively in one direction to settle on the target. If the tuner displays the wrong octave, harmonics are confusing detection. Pluck harder, move closer to the mic, or briefly use the lock mode to anchor the octave.

When to Use a Chromatic vs Instrument Tuner

Use a chromatic tuner for unusual instruments (mountain dulcimer, oud, sitar), microtonal music, or when you need to tune to a non-standard pitch. Use an instrument-specific tuner (guitar, ukulele, violin, etc.) for everyday tuning of common instruments: they are faster and less prone to octave errors.
