A Video Game Music Composition Contest!

Welcome to the LeetChord Jam - a monthly video game music composition jam based on a unique creative limitation! 🎮 Be sure to join the discord for access to free music composition resources, tutorials, and community discussion:

Theme: 🪽Wingman at a 🇯🇵 Festival

In Dating Sim video games there is often a "wingman" or "best bro" character who assists the main character in their escapades and antics for wooing over their romantic interest. For example, the GOAT wingman Umehara Masayoshi from the Amagami games. Given this, the theme will be wingman - write a "wingman" theme for your companion through a Matsuri (祭り) festival. (or it could be a wingwoman, genderless, a wing-koi-fish, a wing-mystical creature, the sky is the limit as long as it is wing-something).

Limitation: Sankyouku (三曲) Ensemble

You must incorporate at least one of the Sankyoku instruments (shakuhachi, shamisen, or koto) as if this were taking place in a Matsuri (祭り) festival. This list may prove to be useful https://en.wikipedia.org/wiki/Japanese_festivals#List_of_famous_matsuri (it is by no means comprehensive though; feel free to branch out to other regional Japanese festivals). You may use any other instruments, as long as you use at least one of the following three (shakuhachi, shamisen, or koto). Taiko drums would probably be a good idea as well, but you are not required to use them.
