Im trying to make a program that can detect guitar chords. A random chord is shown, and then the user has to play the chord. The program detects if it is played correctly, and then shows another chord.

I grabbed this code online and think its a good start

I dont have that much experience with this type of stuff but I learn fast

[lime parrot]

Do you have any specific problem?

[north tapir]

yes, I dont know where to start

[north tapir]

I feel like this is a pretty hard project tho

[sturdy mirage]

What's your experience in Python?

[north tapir]

very basic

[sturdy mirage]

I know nothing about this topic, but: If you're a beginner at Python, you should probably start with simpler projects

[north tapir]

maybe if someone can give me the steps I need to take in order to work on this project

[north tapir]

I mean I can work with loops and functions Ive made basic programs

[sturdy mirage]

Have you done anything with audio?

[north tapir]

not in python no

[sturdy mirage]

The first step in projects like these is to understand the problem: How does one detect chords?

Is this a ML training project? Are you using an existing tool (like Chordino?)? Is this spectrum analysis? I genuinely don't know, but googling shows a number of chord detection projects with different approaches.

[north tapir]

alright thanks

!pypi chord-extractor

[willow patrol]

chord-extractor v0.1.2

Python library for extracting chords from multiple sound file formats

Released on <t:1667588871:D>.

[north tapir]

I think I dont have enough experience to do this in a months haha

[sturdy mirage]

Is one example

[north tapir]

I might just make this a long project and study the theory behind everything I do

[sturdy mirage]

It's kinda a hard project. I know Python quite well, and I wouldn't know where to start.

[north tapir]

I have this code as a start

[sturdy mirage]

This is a great idea. Studying the theory and coming up with a concept is a good plan.

[north tapir]

so Imma start with understanding how that works

that one just uses the mic and can detect which note is played

[sturdy mirage]

Second: Take a look at other projects. I see some projects using a ML approach (training on recognizing chords), and others using spectrum analysis, etc

[north tapir]

where can I find projects the best way

any site recommendation?

github?

[sturdy mirage]

tbh, I would just google "python chord identification" or recognition

[north tapir]

alrighty

[sturdy mirage]

But, I'd be looking for google hits on github

Also, use #data-science-and-ml if you have questions about implementing this (or a help thread like this). The tough part is: if you don't know how you want to do it, you really have to hope you find someone who already knows the answer/has experience.

Once you have a plan, then it's easier to help you.

This is an example of a ML approach: https://www.youtube.com/watch?v=DOOA_kaiHSo

[north tapir]

Imma check that out

[sturdy mirage]

How I'd do this is - survey a few projects and yt videos and see how other people hve done it. Everyone does something different.

[north tapir]

alr thanks man
