 This is a sound theme designed for KDE Plasma. It features instrumental and skeuomorphic sounds, it follows [freedesktop's sound naming specification](https://specifications.freedesktop.org/sound-naming-spec/sound-naming-spec-latest.html) and it was made with [LMMS](https://lmms.io/) and [Tenacity](https://tenacityaudio.org/).
 
 You can get it from [Pling/KDE Store](https://www.pling.com/p/2134858/) or directly from [its Git repository](https://git.gianmarco.gg/gianmarco/harmony2) where I also include the project files.
