Here's Victor Seven, the composer of BuendiaGames, writing about music! Nice thread :D

Even when I think that my music does not fit perfectly the game, many comments say that the music it is very beautiful... So maybe you can take a look to it! https://itch.io/jam/gmtk-2019/rate/461782

 I had a big problem -I had no available piano during the composition, so I everything was recording on-the-fly, first think I thought of... It was difficult, but the themes are catchy in my opinion :)

Loved your music for this game! It's light and fun. The sound design was also very interesting. Made the game feel very unique. Well done!!!

OOf. Also here's my teams submission: https://itch.io/jam/gmtk-2019/rate/463980

I had a lot of fun with the music!

I spent maybe 2 hours at most on the sound in my entry (not a lot). It's a simple game, simple sound design, 1 instrument. Just random notes and chords and arpeggios all in the same key. Shooting in just a note, killing an enemy got the chords, and a sun shot was a quick arpeggio. I think it came out really well and is a highlight for my project. (Especially because it didn't take long)

Rated your game. I really liked the concept and the music was great! Here is mine: https://itch.io/jam/gmtk-2019/rate/461862 

I recorded my backyard at night for the ambient sound of the game. I also played around with 2D audio depending on where the car was. I didn't have much time to really play with this, but I also lowered a low-pass filter on the car's engine as it moved farther away. Sound design is a lot of fun and I would like to focus more on it in the future.

I absolutely love the music that my music guy made. I’m sure we’re all biased to our own game’s music, but it’s the perfect match. The music was made by Devast8, one of my composer friends, and he killed it, please check him out.

I can’t really talk about the tech behind that, but what I can talk about is the voiceovers. These were so much fun to make, I just took on the role of these strange characters and ran with it. The main, raspy voiced character was just me talking in a very raspy (and kinda crazy) voice. One of the endings features a long monologue from him, which is so good. There was this other character that I was going for a reaper like effect, very deep and echoey. The first few times you hear him, he’s muffled, achieved by overlaying multiple pitches of the same voice sample. He’s also rather bassy, giving them a powerful stature. 

All these things are probably pretty basic in comparison to an actual sound artist, but I’m happy with how it turned out. You can play (or listen) here: https://justcamh.itch.io/tunnel-view

Hey there! I won't have much to say, but I'll say a little bit about the sound of my entry, Flight Of The Electrodud (https://thatjdude.itch.io/flight-of-the-electrodud), because I got some positive reviews for the sound and music. And for the record, I'm not specialised in sound design.

I made every sound effect and the music just using Bosca Ceoil and Audacity. I created the "build up to thud" sound effect with just a long reverse symbol sped up a bit, and I created the thud sound effect by just combining a bunch of bass noises with a low melodic tom and bass boosting it a little bit.

As for the music, I just wanted to create a short, simple, and hopefully catchy tune that reflected the game's tension of "one split second of waning focus and I'm probably gone" while still being fun. (I was going to make it just last the full minute, but I know my limits, and that would've taken too much time for it to still sound good.) The menu jingle was simply meant to be appropriate as both a "welcome" and "goodbye" jingle, since it's where players are most likely to, well, stop playing, as everything loops back to the menu. And the victory jingle is just... triumphant, I guess. Oh, and every bit of music/jingle was slightly bass boosted.

But I think one of the main things that helped tie it together was that everything, sound effects and music, were in the same key - G minor. made thudding to the ground in time with the music that much more satisfying.

I voice acted the sound in my game (missed a whole day of the game jam so it could be more polished but I'm happy xD)

Having played bass guitar a lot back in the day, I was very happy when I sold the "slap bass song" idea to the rest of the team :P Although recording everything was harder then expected, I'm pretty happy with what I ended up with. The hardest part was getting percussion right as I couldn't use actual drums (at the time there was too much background noise to use microphone for anything), so I had to do them on the keyboard which just didn't work out.

Anyways, if you want to check it out, hit the gong:
