Questions about the online tuner and instrument tuning.

Q. What is an online tuner?
An online tuner listens to your instrument and shows whether the pitch is sharp or flat. You can tune on a computer or phone without a separate tuner.
Q. How do I use the tuner?
Choose the instrument, then play one string at a time. When the tuner hears the note, adjust the string until it matches the target pitch.
Q. What are the standard tunings?
Each instrument uses different strings. Guitar is E-A-D-G-B-E, violin is G-D-A-E, cello is C-G-D-A, and bass is E-A-D-G. Ukulele and viola follow their own standard tunings.
