I have always been able to create music in my mind. "To orchestrate is to create, and this cannot be taught", wrote Nikolay Rimsky Korsakov !
"Good composers borrow great composers steal", so said Igor Stravinsky
There are no rules listen to the music pleasure is the rule, so said Claude Debussy
( What we do in life echoes an eternity )
(Footnote) my music is written to sound its best using electronic sounds,some notes and tempo may vary.
