Slash playing guitar in front of the church in the November Rain video was the coolest thing I ever saw and I wanted to do that at all costs. That started my guitar playing career 30 years ago.

For writing: I find that writing songs comes easier when I have something I want to say or talk about. Trying to write lyrics without that doesn’t work for me. I need a theme or a message.

There’s no one answer to how to do this, you just have to start.

If you want to start with vocals, study melodies and hooks.
