The pieces gathered here have been composed over the years for exams of municipal conservatories in Paris and the Paris region. Retouched and completed, they are sorted in ascending order of difficulty, in two notebooks corresponding roughly to the first and second cycles of studies. The author considers that it is natural to start with pieces of tonal style, the notion of tone also including that of clear form, because nothing is more confusing for a young student than not to feel guided by a speech harmonic familiar. That is why these pieces are written in a resolutely classical style, with all the nuances that this delimitation supposes. The piano part, which is often quite difficult, should as far as possible be entrusted to a first-class accompanist, capable of leading the discourse as if to fade away, to emphasize the effects of counterpoint, modulations, etc.
