No, I had not heard of this Spanish genre (cuarteto) before choosing it to create this track; you learn something every day!
A week or so ago, I decided to slow down producing songs, infavour of experimenting with more genres on Suno's list. And here I am admitting that I did not even know what some of them sounded like. OK, todate I have been experimenting with my old songs, most written decades ago. This meant fitting genres to the songs.
Here I try to sing Suno some of my melodies, and to understand what the genre will sound like. S that It may be possible to write for the genre, hopefully getting a better track/song from doing things this way around. Stepping out of my comfort zone so to speak.
Hope you like some of the results from this "research" project.
