I am in the planning g stages of building a visual pentatronic music box. Using 5 different colored tubes, that light in rhythm to a pentatronic song...

If you get stuck then perhaps take a look at this book by Mike Cook:
https://www.apress.com/gb/book/9781484217207

It has a couple of chapters which may be relevant depending on your project.

Ch16 covers sampling of real time audio on an Arduino Uno using the Open Music Labs FFT library:
http://wiki.openmusiclabs.com/wiki/ArduinoFFT?action=AttachFile&do=get&target=ArduinoFFT2.zip

Ch17 covers real time sound to light using an Arduino Due with the SplitRadixRealP.h FFT library
https://coolarduino.wordpress.com/2014/09/25/splitradixreal-fft-library/ (currently broken so try here:
https://github.com/pierinz/randusynth/raw/master/SplitRadixRealP.zip )
and displaying it on 240 Neopixels

If you can post some more detailed information about your project, where you are at with it, and what the problems you are experiencing, then you are much more likely to get more chance of help from the community.

You may want to take a look at the Cornell ECE 4760 AVR microcontroller course on YouTube as part of it covers audio synthesis on the AVR platform.

Here is one of the student final year projects for an audio spectrum analyser using Atmel ATmega1284 microcontrollers:

Full list of student projects is here:

there are at least a couple more doing audio synthesis:

https://www.youtube.com/watch?v=bZ4p090KL3w&t=0s&index=35&list=PLEB09A7C8641987A8

I suspect that Mike Cook's book would be a good reference for you to start with however.
