Online Cello Tuner

Use this free online cello tuner to tune up your cello. This is for the standard CGDA cello tuning. Click on the note for the string you want to tune and then adjust the fine tuner, and tuning pegs if necessary, to match it up with the note that is being played. Also you can use this online tuner for your viola, it is the same tuning.

It sucks. Not even a real note so it’s impossible to actually and accurately tune the cello

Dear Homophobic

On behalf of every gay person in the world, We’re sorry you feel this way about us but how is it any different from likeing people of the opposite gender. If gay people hated and feared straight people and it was accepted by almost everybody to be gay and some people hated straights and claimed it was against ‘their beliefs’ and I wrote the same thing you did and would you be writing this comment? In the end we all look the same inside and we all bleed the same. (Especially when I gut you like the rotting carcass you are and hang your head on my wall as a trophy)

I have a question, I just got a string replaced and my cello when I play has a weird buzzing too it. I was wondering if anyone knew what was going on and how I can fix it

isn't it weird that a cello tuning website gets this many comments!

by jessie on

It's ok

Didn't tune my cello properly it was off a little bit. The notes were also very confusing I didn't know which were the original note names
