Why Regular Piano Tuning Matters

Pianos go out of tune even if you don't touch them. Heat, cold, and moisture change the strings inside. Over time, the notes start to sound wrong. Using a piano tuner often keeps your piano sounding clean and clear. It also protects the parts inside from getting too loose or too tight.

Regular tuner for piano helps it last longer and play better, whether it's for home use or live shows. Even if you own a digital model, the action and feel benefit from routine checkups. Our tuner for piano makes it easy to get precise adjustments anytime.

Standard Tunings for Piano

Most pianos follow one main rule: the A key above middle C should sound at 440 Hz. People call this A440, and it's used almost everywhere in the world. Once that A key sounds right, the rest of the keys are tuned around it, step by step. This keeps all notes even and smooth.

When using our piano tuner, start with the A4 key. Make sure it matches 440 Hz, then fix the other keys one by one. For digital pianos, A440 is usually already set, but you can still check it to be sure.

Perfect for Other Instruments Too

Our online tuner works beyond pianos. You can also use it to tune:

• Guitars and ukuleles
• Violins and cellos
• Other stringed instruments

Whether you're at home, in a studio, or on the go, this piano tuner tool is built for convenience.
