Grade 8 ABRSM Music Theory - The Trio Sonata Question
Question 1 in the ABRSM Grade 8 Music Theory exam asks you to complete a Baroque Trio Sonata, which is given to you in a partially completed state. Many students beginning to study at this level have no idea what a Trio Sonata actually is - so don't worry if that includes you!
Here's an example of a Trio Sonata by Corelli. It's a piece written for three instruments and follows the traditional rules of harmony and chord progressions.
The bass part of the composition would have been written for a bass instrument such as cello or bassoon, but would also have been doubled up by a "continuo" player - someone filling out the harmony by improvising an accompaniment on an instrument like the harpsichord. The "figured bass" under a bass part stave shows which chords the continuo player would use.
In the grade 8 exam question, you need to use the given figured bass, and take ideas from the part of the sonata which has already been completed, to fill out the whole excerpt.
