Thanks. That's a broad question but I'll try. First of all, know music theory. There's a group that can help you learn a bit (it's called Music Theory), but it's not magic. Getting comfortable with the notes and how to use them is key, no pun intended. Then, start foolin' around with the instruments and see what you can do. Always ask for input and advise as well, that's why soundation is public. And lastly, plagiarize. Well, sort of. Listen to what other people are making, and try to copy it and learn from them.
Hopefully this will help, and always remember that skill comes with time.
great song. could you give some tips for a new guy?
