I also have a B.A. in Popular Music (which is about jazz & Brazilian music, not Madonna,
unfortunately), from IA-Unicamp. I play the bass (both bass guitar and double bass), I compose
some stuff and I also enjoy producing my own indie songs. I try to play some piano and
drums as well.
My bass professor at Unicamp was Zé Alexandre Carvalho. He was also the supervisor for

- Mutação, for solo double bass. This piece uses a composition process which is based
on I Ching (the Chinese divination system). Supervisor: José Augusto Mannis. (pdf)
- piano forte, for piano. (I consider this to be my best composition, technically speaking.)
Supervisor: José Augusto Mannis. (pdf / audio soon)
- variação sobre 8 cordas, a double bass duet. This piece is based on Anton Webern's
Variationen, Op. 27. (One might have a lot of fun playing this with a friend.)
Supervisor: José Augusto Mannis. (pdf / video)
- Mother Mary, a theme and variations for piano and computer. (The last variation is
one of my favorite works.) This is deticated to my mother, Maria.
Supervisor: Denise Garcia. (pdf / audio)
- Traduzir-se, a song for mezzo-soprano and piano. Lyrics are extracted from a poem
by Ferreira Gullar (which I do not own). This was composed to be sung by my friend
Maria Cordélia. Supervisor: Denise Garcia. (pdf)
- Boteco, an electroacoustic sound narrative. The jazz piece is from "Beard" by Blur
(which I do not own), and other samples are from freesound.org.
