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.
