Biamonti 104 – Unused sketches for the piano sonata in E major Opus 14 number 1. Among the numerous sketches for the piano sonata in E major Opus 14 number 1 existing in a notebook preserved in the British Museum in London and reported by Nottebohm, there are some that were not used later in the final version. According to the aforementioned scholar, they would belong (from whose work we faithfully report them as they were written, often without indications of key or tonality, or tempo), to an era not later than 1795 (while the conception of the sonata must be placed in 1799) and there are three: the first concerns the central part of the development of the first movement,  the second refers to the trio of the Scherzo, the third to the rondo – finale.
