I propose courses or a help to musical work for the following disciplines: musical training (solfeggio), cello, piano, bass guitar, adapting to the needs of the student (theoretical or intonation gaps). I also propose, parallel or mainly, an introduction to improvisation. I do not have a prefabricated pedagogy, although I am inspired by the best that all my teachers could give me. On the other hand, I report on the progress of my program, and if necessary, I have a weekly personal work by the student (believe it or not, sometimes it helps!). See you soon. Martin.
