Does anyone here composes or wants to compose music?

I know how to play the bass guitar and electric. Ive written some music for myself. The best way to get on the track to writing your own music is to write lyrics and then make up the instrumental in your mind then just convert that to the instrument. I dont know how you would go about an instrumental only piece and im in no way an expert on music theory. I just love music that sounds good to me and thats how i would get the effect that I wanted.

When we say orchestral we tend to think of classical music. but you also say film music. Much film music needs to be classical (also think hostoric period pieces) but film music also crosses genres to produce "emotion" rather than pander to stereotypes. Think of science fiction films. Many have classical underscores (Space Odessy) but also scifi films can also have very futuristic synth orchestration, instead or in additiion to. And how many action films would miss out if they didn't have a modern dance style drum beat under pinning them, such as in chase scenes. I only mention this because different stereotypes of music require difererent composing and orchestration strategies. But one thing tends to be common across all composing. Picking some sort of motif, hook or melody. Which ever name you prefer. Then there are 14 techniques (and more) to extrapolate these out in to the sections (like verse and chorus) that we have come to expect. These 14 are probably outlined in your music theory book. I haven't read that one myself. There is no right or wrong answer and personally I have used all of these starting points to compose; 1) A song title or key emotion or lyrical phrase 2) Lyrics. Usually 1 or 2 lines in the initial inspiration 3) A rhythm, I say rhythm and not drum beat or drum loop, because I may hear something organic or mechanical that has a rhythm in it. Lieka train carriage rattling. 4) I may have a few (4+) notes of a melody, riff, or motif. 5) I may have a chord sequence. Most likely I will have several of these spinning round in my head from before, and finally they piece toegether to speak the emotion of what I want to say.
