I'm Anass, I'm a Pianist and a Music Producer, I have turned professional lately, but I have been doing music since I was 8, making it 14 years now.
As you can tell, nothing really makes me happier than sharing the art I create, so if you're really looking for someone to collaborate with and create your own original Intro Music, I'll be really happy to help!
Check out my social media and my Youtube Channel and see for yourself, don't hesitate to contact me!
You could try creating a mood board for the image you're hoping to achieve for your channel. Then you can brain storm different musical pathways and perhaps narrow down to certain styles/genres. It all starts with a strong image in mind.
Check out https://pyramidtracks.com real cool royalty free music (I am an artist there)
Also https://premiumbeat.com is very good
I use the Free Youtube audio library and you can search based on the mood :-D I usually go to the electronica or hip hop section and then choose the emotion (inspirational, moody etc) https://www.youtube.com/audiolibrary/music?nv=1 hope it helps
