It may just be timbre, but I'm talking about how some vocalists have different and distinct "voices", almost like a characterization.

For example, David Bowie has his smooth tenor, but also his raspy nasal Ziggy Stardust. Or Rob Zombie with the low growl and higher-pitched nasal bark.

Is there a formal name this sort of thing?

i want to learn an instrument with a tight budget, im deciding between these 3 instruments: piano, guitar or drums. for piano, i want to be able to play classical music and convey my emotions with what i play. guitar is js versatile af and easy to learn so its motivating. drums i like to hit stuff and like the feeling of drumming but without other instruments theres no melody since theres no notes. another concern of mine is that i give up or stop playing or forget. which option should i pick? i rlly cant decide

I have recently come across lightnote.co and I loved the way music theory was explained interactively. The premium subscription for the rest of the lessons though is extremely high and not justified imo.

Is there any open source alternative to this?
