I would love to find a beginner's guide or even a rough start for Arduino or microcontrollers that's music and audio oriented. Does such a thread or tutorial exist?

I'm not aware of a specific beginner thread. Most or all of the threads will be rather specific for a particular subject. Also, the way these forums work, there can be deviation from the thread title and the thread can wander significantly.

Part of the problem is that beginners are not all the same, some have skills that others don't. So asking questions here about the specific things you would like or need to learn will probably be more helpful. Do not worry about asking questions that you might think are too simple, there is no such thing here and you will receive kindly and respectful responses.

Indeed, it would be helpful to have such tread. Maybe this one?

There are two main areas of Arduino music applications:
- first: direct sound creation by Arduino,
- second: Arduino as a controller for the other sound-generating hardware.

Standard Arduino microcontrollers (like Arduino Uno, Nano, Mega) have rather poor processing power so although direct sound generation is possible, it may be attractive maybe for beginners as capabilities are not very impressing (at least for me).
Sound can be generated by different methods:
- PWM,
- digital synthesis (procedurally generated),
- wavetable synthesis.

As I am completely not interested in this area, it is up to others to continue this subject eventually (powerful Arduino controllers like Teensy 3.5/3.6 or even Zero are quite different piece of cake and should have separate thread).
You may start with Mozzi library for Arduino sound generation:
https://sensorium.github.io/Mozzi/
https://github.com/sensorium/Mozzi


Arduino may be a perfect inexpensive controller for other music hardware:

- Arduino MIDI processor:
-- MIDI receiver and transmitter,
-- MIDI router,
-- MIDI to CV converter,
-- MIDI clock,
-- MIDI all-in-one (all of above);
-- there are different MIDI libraries for Arduino but my favorite is here:
https://github.com/FortySevenEffects/arduino_midi_library/tree/dev
with docs here:
http://fortyseveneffects.github.io/arduino_midi_library/index.html

- Arduino as a control data processor:
-- processing data for waveform generators (e.g. based on Direct Digital Synthesis, like AD9833 chip),
-- processing low-speed data for DACs (envelope generators, LFOs).
-- Grumble threads here show some examples.
-- example library for Arduino AD9833:
https://github.com/MajicDesigns/MD_AD9833

- Arduino as user interface processor:
-- encoders, potentiometers, switches reading,
-- LCD, LED, OLED displaying data
-- examples everywhere in the net.

- Arduino as a carrier for sound-oriented shields:
-- MIDI shields (like SparkFun Midi Shield),
-- sound generation shields (shields with VS1053b chip are capable of generating General MIDI sounds - Waveshare, SparkFun, better are shields based on SAM2195 like Fluxamasynth Shield),
-- speech synthesis shields (like MOVI Arduino Shield or DFROBOT Arduino Synthesizer Shield).

Jchot:

When I was getting started in Arduinoland, I got into "Tinkercad" which is a decent Arduinio simulator that's free.

So you can learn basic skills--say, delaying a gate signal, controlling a CMOS chip, lighting LEDs, seeing PWM output on a scope sim, etc etc without having to buy a single part.

I have found the sim to be very useful when going from design to actual build...just copy your code and whatever is on your breadboard.

Main issue to me: when the sim gets complex, the site slows WAAAYY down, but still worth signing up IMO.
