Well my friend, you need more practice. And you're missing some chords by the way. I know Mexican music has a complicated rhythm, specially "el son de la negra" but you really need more practice
El amigo es estudiante de vihuela extranjero, eso ya de por sí complica mucho las cosas. admirable el trabajo que hace, y sobre todo que estudie una música que no es la de su cultura.
I am impressed, young man. keep it up. May I suggest you look up "Mariachi Samurai" 100% Japanese Mariachi Band who plays at a very professional level. Good luck.
You need more practice, my friend, there are many maniacs of the son that do not work out for you. And besides, you don't leave on time, you lose your beat a lot, rehearse with a metronome so that you leave on time.
Hello! It's cool seeing your vids and your learning experience. You should purchase a finger pick to use while playing your Vihuela, it helps give the "power" that you need while playing songs, especially Sones.
