Frequently asked questions
What are the ukulele string notes?
Standard tuning, from the string nearest your chin to the one nearest the floor, is G4, C4, E4, A4: “Good Cats Eat Anything”. The G is higher than the C (re-entrant tuning), which gives the ukulele its bright sound. Low-G tuning drops that string an octave to G3.
Should I use high G or low G?
High G is the classic ukulele sound and what most songbooks assume. Low G adds a deeper bass note and suits fingerstyle and jazz. Low G usually needs a thicker or wound string, so check which string your ukulele has before tuning it down.
Why does my new ukulele keep going out of tune?
New nylon strings stretch for a week or two. Tune up, gently pull each string away from the fretboard along its length, and tune again; repeat until it holds. Temperature and humidity changes also detune ukuleles.
Is my audio recorded or uploaded?
No. The tuner analyses the sound from your microphone in your browser, a few times a second, and throws it away. Nothing is recorded, saved or sent to a server.
Why does the tuner jump between notes?
Usually because more than one string is ringing, the room is noisy, or the note has faded. Mute the other strings with your fretting hand, pluck firmly, and read the needle while the note is still strong. Moving closer to the microphone helps on laptops.
