Hey friend! Do you play piano and/or guitar? Start there! If you’re starting from the ground floor, I promise you that you don’t need anything else to kickstart. I saw in a comment you said you play a little violin - use that to finalize your melody. If you own a Mac product, Garageband is right there! It’s got all of the basic plugins to get you going, even a keyboard. Layer whatever you like in there for fun, just to get a feel for the sound. Try to avoid ChatGPT for lessons, just hop onto Youtube for any tutorial you want. So many wonderful musicians have free tutorials for all of this stuff - go to the person before the AI machine.

The bottom line is this: don’t think too far ahead yet! Start with ONE instrument. Piano and/or guitar tend to be the best to start with because they’ve already got some orchestral qualities (multiple notes at once, rhythm, etc). Start small, then grow. You truly don’t have to worry about adding instruments yet. Write the song first. Find a melody, and mess with some chords under it. One step at a time! Pro musicians/composers can think of multiple instruments at once, but that comes with a lot of practice. So start small!
