Hello all, I am new to the forums here, although I once had an account a while ago, and rarely used it. But now, I've returned, and with some very difficult questions for you all: first off, let me state that I am a young teenager, and have played French horn for 4 years in my school band, beginning in middle school. I loved the horn, and practiced a lot, quickly advancing to where I am now, the 1st chair of the high school marching and concert band. Now, along the way, I had never, ever thought of music as a possible career. But then, I started getting ideas for compositions, though my musical knowledge was greatly limited; all I knew was basic notation, etc. My dad had purchased GarageBand for our Mac, and I soon set to work recreating the sounds in my head, on the computer. At first I had no luck, and even when it started to come together, the rhythms were mostly off. Anyhow, by this point in time, I have a pretty good grasp on rhythms and notes, although I still lack the proper training. Up to now, I have merely written what sounds good to me. I am heavily influenced by the music I listen to, but I still don't know too much. Granted, I do know certain things, like major and minor chords, how to determine the key of a piece based on the flats and sharps in the key signature, how to create chords, some basic knowledge on transposition, some knowledge on instrumental articulations, and a brief understanding of what counterpoint is. But, as you can tell, I still have a lot to learn. Does anyone know of any good books or sites that could help me?
