Yes! I make music for my comic!
My comic has three volumes of soundtrack so far, and I've almost finished a fourth.
Volume 1
Volume 2
Volume 3
And
My Comic
It's a sci-fi about retired magical girls forced out of hiding to look for answers regarding their past.
I also make music for other people's comic, like the time I wrote one piece a month as a gift for another creator for a year, this piece I wrote recently for someone else who I first met on these forums, and this EP I wrote for Serpyra's comic Vindicaris.
...I'm something of an enthusiast for webcomic music, so I'll be sure to listen to everyone's work in this thread
As far as tips for music making go...
- Use reference. Steal chord sequences and rhythms. There aren't actually that many different chord sequences/rhythms possible, so it's basically impossible to copyright them.
- Good melodies are 70% rhythm, which is a lot easier to come up with than pitches. Once you have a good rhythm for a melody, finishing it off becomes a lot easier.
- For radio-length instrumental tracks, always begin quiet and build up to the main theme/something really exciting at 30s. It's the pattern folks are used to from pop music, and it's useful for keeping people's attention, since most people don't tend to listen to much instrumental music.
- Always record your own sounds where you can. Sampling is the single most powerful invention ever. Every sound you sample yourself is a sound no one else has ever heard before. Even if it sounds awful, it's special - it's yours, and it's unique. Processing samples afterwards is an art form in itself, and definitely worth learning. For more on that, I recommend Christian Henson's and Andrew Huang's YouTube channels.
- If you just want recordings of spoken voices just saying stuff, be it dramatic monologues, or quotes from books, Librivox.org is a website full of public domain audiobooks. I use it all the time if I need a quick line or two of spoken word.
- Free resources-wise, I can't speak highly enough of Synth1, Spitfire LABS, and Pianobook.
- Never underestimate the power of 8bit music. When producing 8bit was the only producing most computers could do, the internet was a very different place - at first it didn't exist! But, when it did, lots of the resources and samples were free. Out there, there are massive massive archives of sounds waiting for you to use them, all for free, that haven't been touched since the 90s. The ST-01, ST-02, and their successors, the KI archive, Odo's archives... I leave these unlinked for you to discover for yourself. Half the fun of old music resources is tracking them down in the first place. Because, you never know, you might find other cool things in the process
Thank you for this opportunity to share my work! My comic soundtrack is mostly something I do just to push myself, and it's very scrappy in places - personally I think my other work is of a much higher standard... but I really enjoy making it! Please let me know if any of these tips were helpful!
