Guys from Ug, do u have any idea how ppl like joe satriani, steve vai, paul gilbert compose their sonds? Pls Help Thx
They just write it for themselves.

It's the same method as writing for lyrical songs, just without the lyrics - meaning you can go crazy. I reackon they hire bass players n drummers to play for them however
They know their theory, I believe Joe Satriani's 'Surfing With the Alien' is just a really long guitar solo.
lots of interludes. experiment with what works and not. when your writing, try and aim for a mood in the beginning. lots of interludes
curently composes with Guitar Pro 5. amazing peace of software. i'd recomend it. and Samplitude recording studio.
