PyTuner: A Guitar Tuner In Pygame

A Guitar Tuner that I wrote in python and pygame. Tested with 2.7 and 3.2, works for both.


PyTuner is a guitar tuner that I wrote in python and pygame that has a simple GUI made entirely with pygame's draw functions. Version 1.0 features 4 different tuning scales: E Standard, 1/2 Step Down, Drop D, and C Standard. More will be added in the future. If you want any further information, feel free to email me at

Thanks for downloading!

    nice.  looks like it suits a touchscreen interface nicely.

     Thanks! Yeah now that you mention it, it does seem like it would work well on a touch screen although i haven't tried it myself. I am currently working on the GUI a little bit more and adding some more tuning scales as well. Thanks for viewing my page!

    It looks nice. I got fresh news on this August.. :D

    JDSmith5896 2012-08-12 01:48

     Thanks! I'm working on the next version currently but it will be out by late august. This next version will feature a custom tuning system so you can choose your own scale and then save that current tune for later. Binary version is coming out soon as well.

    Looks good man, maybe you should try improving the text quality?(maybe just on my pc?). You could try to specify a standard windows font :p

    Guest 2012-08-22 03:13

    Yes i do agree with you, the text is not that good of quality even on my pc. It's all a work in progress and the next version is going to have a few more features such as themes, custom tunes, etc. Thanks for the feedback and i will add this to my to-do list!

    Yes the text has bad quality even with my pc. It is all a work in progress, and with the next release i am adding a few more features such as custom tuning. Thanks for the feedback and i will add it to my to-do list.

    A tuner maybe should be capture a input sound and show the frequency of this, no?

    Matthew 2012-11-04 18:51

    Absolutely a good idea-- a working implementation of a "main-frequency-finder" would be great. I feel sure pygamers would love to see one as well. : )
    Though I wonder how complex such an algorithm would be, (as well as what it's called) I'm guessing it's a very complex algorithm?--I believe a single sound actually has multiple frequencies happening simultaneously and only one must be chosen. . .

    Fast Fourier Transform - This will allow you to find the level of each frequency and then you simply need to pick the one with the highest power.

    Fast fourier transform of what? how to get a neat (discrete) math function from the audio input?

    JDSmith5896 2012-08-24 05:44

    Yes you are correct. However, this is my first ever project on python/pygame and i haven't found a suitable means to do so currently. This will be added in the future but it will be a while.

    Very nice game1

  • Wojtek 2014-12-22 12:01

    Hey, I downloaded the tuner and gave it a go, I like how you made it! I checked the code and there's a lot of big conditionals and if statements, like this:

    if pressed =='red':


    elif pressed =='orange':


    elif pressed =='yellow':


    elif pressed =='green':


    elif pressed =='cyan':


    The advice is about two years two late lol, but it's easier for a programmer if you make a dictionary where orange corresponds to 1 and so on. Then you can have

    if you don't want download programs you could check this online chromatic tuner

    I learned about Py in college, but never imaged a Tuner app being coded in it.
