Hey, anyone can hand me some guides over basic contents over composing and harmony?

I'm a total noob at theory, but i mostly do ad-hoc checkups in Wikipedia whenever i want to grasp something. There's also this book, Harmony for Computer Musicians i have, which i never got around to read in its entirety, but it seems nice enough. Also we have a dedicated section here, in this very BotB's Lyceum too

This and this

Open Music Theory

looks like a comprehensive textbook covering the sort of music theory you might study at a conservatory or college course, if that's the sort of thing you're looking for.

Thank fellas. And Petet, yeah kinda, I want to comprehend better how music is constructed.

I'm looking for jazz theory tuts
