References, voice notes, demos or melodies.
Send the references. Show the energy. The beat gets built around your voice and your record.
Start a beat
Send a few songs you live with, a melody or a rough demo. Mertz looks for the common thread and builds from there.
References, voice notes, demos or melodies.
Beat, arrangement and space around the vocal.
Record in the room or keep working remotely until it lands.

The point is not to copy the reference. The point is to understand why it hits and make something that belongs to you.
A YouTube link and a voice note are enough to start.
