Example 1

The opening of the “trio” section of the last movement of Clementi’s Op. 7 No. 2, an example of the kind of octaves that Mozart mentions in his letter of 7 June 1783. This is taken from a copy of the Artaria print that Mozart might have seen. Performed by Erin Helyard on square pianoforte, John Broadwood and Son, London, 1796.
