As classical trombone player, working with Willy has been a wonderful experience both personally and musically. Thanks to his extensive knowledge of jazz harmony and trombone technique, he was able to support and guide me in the best possible way throughout the lessons we had together, with in-depth teaching and a friendly approach that allowed me to better assimilate the points we worked on.

Thanks to his lessons, I am now much more comfortable improvising, reading charts, and playing in an JAZZ set up.

Thank you very much, Willy, and I look forward to continuing the work we have already begun together. - Leonard de la Serviere
