Every year, Dario Napoli organizes a gypsy jazz camp in Italy by the middle of June known as UTTS (Under The Tuscan Sun) where @Eva Slongo was teaching jazz violin for several years. 2026, at the 11th edition, we were only 4 violin players, this time with Roland Tillmanns, Phoebe Forsey, an English Lady and myself. This year the violin teacher was Christiaan van Hemert. I understood from 4 days of morning lessons that his approach to jazz violin improvisation involves: - Simplification of the chord changes (2-5-1 becomes 5-1, dominant chain, Christopher...)  - Constant awareness of these changes, “seeing” chord symbols in his mind's eyes rather than hearing them. Singing is not his preference.  - Chord symbols trigger automatized arpeggios and scales with or without permutations and approach tones (playing “dirty”).  - Hardly any licks at all  - Only the meta level (the big picture how to navigate the changes) remains conscious  - His practice strategy focusses on a tool he calls "Creative rerun" to develop vocabulary consisting in connecting automatized scales and arpeggios following the changes
