The Musician Behind the Scores
My musical training includes a master’s degree at the Rotterdam Conservatory (Codarts), where I graduated as an electric bassist specializing in Brazilian music and latin-jazz.
I had formal training in classical double bass, trombone and also sound engineering in CES in Madrid.
Over the years, I’ve attended workshops and clinics from leading musicians such as: Richard Bona, Gary Willis, Guillermo Klein and Andy González to name a few.
I have been teaching music theory, electric bass and conducting ensembles at the University of Cádiz since 2009 and combo workshops at El Musicario association since 2014 without interruption.
As a bass player, I’ve collaborated with artists such as Chano Domínguez, Jorge Pardo or Julián Sánchez among others.
I regularly play and record in projects ranging from latin-jazz to rhythm & blues or brass band playing electric bass, trombone or trumpet.
This ongoing work with real groups and my wide point of view as a multi-instrumentalist is at the core of everything I write.
Educator
I’ve been teaching bass, music theory and ensembles in School of Modern Music and Jazz at the University of Cádiz (UCA) since 2009 without interruption.
Teaching at School of Modern Music and Jazz
This experience enables me to write clear, well-structured and musically solid scores that work effectively in real teaching environments.
Instructor at “El Musicario Asociation”
Every year, I transcribe and arrange more than 100 songs, of different styles for these large groups. More than 50 musicians of different levels. I must create practical, well-structured scores that are easy to rehearse, adaptable and effective on stage.
Arranger
Since 2014, I have been creating and leading combo workshops at El Musicario association, working hands-on with musicians and refining my arrangements through real rehearsal and performance. Also been the band leader and composer of my own proyect, give me a strong view of a fine arrangement from scratch should be.
Musician
I’ve never limited myself to a single musical style, working across jazz, blues and latin music as an active performer.
Playing regularly as a bass player or trombonist on stage keeps my work grounded in real performance needs: clarity, accuracy and readability.
This experience translates into scores that are practical, playable and designed to work in real musical situations.

What Sets These Arrangements Apart
My Approach to Arranging
There’s a gap between what’s commercially available in music arrangements and what ensembles actually need to sound their best. Many arrangements look great on paper but fall apart in rehearsal—impractical passages, bad sensible page turns, poor balance between sections, or writing that doesn’t suit instrument ranges.
My goal is to bridge that gap. Every score here has gone through a rigorous process: transcribed, written, rehearsed with real musicians, performed live, and refined based on what actually works. When you purchase one of my arrangements, you’re getting something that has been proven on stage.
