Depends on the vibe you going for. For example.
This female vocalist sent me a song idea. Just her singing on her laptop mic (a midi piano one not no quantized kind of thing). Her singing put me in the mind of something Chaka Khan would sing....it had an old school vibe. So my thought process is to create something with an old school soulful yet uptempo vibe....make it sound new school.
I'm not going to give the complete list just an example.
Soulful uptempo
So as I listen to her piano notes, I take that idea of hers and create this atmosphere around it. Take the piano and turn it into a bassline and create this vibe. Yet give it a new feel.
Vibe for hip hop pimp shit, east coast boom bap, gutter shit, trap shit. Just creating that atmosphere around me. It helps especial when you do so many different styles.
It keeps me from trying some shit with people's money. I'm quick to come up with some off the wall shit when it comes to me messing around. Sound designing and all of that type shit. Throwing in random shit. For some one else, I go into a state of "shit this has got to be right".
I'll post something with this other singer. It was a new experience for me. It was a shock that she wanted me to do something for her because she sings to Jazz tunes (upright bass only type shit). White girl with a soulful voice. She sent me an idea on her laptop mic. I was amazed at myself.......how good just a laptop mic can sound with a wonderful voice. I'll post it but take it down in 30 minutes. Hell, it was a free collab type thing anyway. It's too much work to do that type of stuff and not get paid. At the same time I do respect the work.
She sent me just vocals. I listened, chopped them up, set the bpm so how I arranged them with be in some kind of timing. (Can't remember some inspiration songs) but I had an idea in my head as I listened to the metronome and her vocals. I removed all the noise in it from the Laptop (she recorded the vocals). Went into reason and chopped up the (never use ever) guitar strums. The rest is history. She listened and loved it. I told her this is just a skeleton....it needs the real deal....guitar player, drummer, more lyrics written, ect. But I had some alternative rock music on my computer that I listen to after it was done. Felt satisfied with it as my first time doing all of that got damn chopping just to make something happen. lol!
30 minutes it comes down.
