This mod adds two new features to the Immersive Melodies mod, those being:
The Echophone - A sculk-based microphone that uses a choir midi sound. Sing your heart out with this new instrument that works exactly like the ones from the base mod.

The Conducting Baton - An item used to control instruments being played by mobs with ease, allowing the player to form bands, select tracks, and change songs all without removing their instruments from their hands.

Things you can do with the Conducting Baton:
Right-click a performing mob to assign MIDI tracks
Shift-right-click to add or remove them from your ensemble
Right-click air to choose or pause the ensemble song
Shift-right-click air to release the whole ensemble
Sneak with the baton to highlight your ensemble
Disclaimer: This mod NEEDS Immersive Melodies to work, which can be downloaded here. Here
