This tuner will require mic access through your web browser. If the needle and strobe are centered and steady, then your instrument is tuned. Make an adjustment to your instrument, either by adjusting a slide, a peg, or whatever your instrument's equivalent is.If you had to bring the pitch down, then you were sharp. If you had to bring the pitch up, you were flat.

Once the tuner recognizes what note you are playing, try to adjust it so that it stays perfectly steady and centered on the dial.

If you play an instrument that needs to transpose, like a trumpet or French horn, then you will need to understand how to transpose. If you play guitar, piano, or another instrument pitched in C, then you will see the note name of the pitch you play. Remember, these notes are shown in concert pitch. You will see the needle move and the strobe rotates until it finds the pitch you are playing. To use this instrument tuner, make sure the built-in microphone has web access. Playing with a tuner will help develop your intonation and an understanding of the tendencies of your instrument. While tuners work by tracking hertz, musicians measure how close they are to the pitch in measurements of cents. If it is flat, it will register as 439 Hz or lower. If an A is sharp, it will be 441 Hz or higher. Tuners work by detecting the frequency of the pitch (sound waves). The accuracy of a pitch is what musicians call intonation. It will let a musician know if the note they are playing is sharp (too high), flat (too low), or if it is in tune.

A tuner is a device musicians use to detect pitch accuracy.
