What I remember of my repertoire at that time...
*Rieding Concerto in B minor (feels really cool to be able to play a whole "concerto"

)
*Kuchler Concertino (in G??) in the style of Vivaldi
*Slow movement from Vivaldi's Winter - sure I murdered this one but at the time it was definitely my favourite piece I'd played so far. It came from a Sheila Nelson book called 'The Baroque Violinist', which also had some other good stuff in it, and there's also 'The Classical Violinist' and 'The Romantic Violinist' at the same level.
*Handel Sonata in F major
*Carl Bohm Spanish Dance
*Paradis Sicilienne
*Elgar Chanson de Matin
*Fiocco Allegro - officially I think this has been grade 6 but I played it way before I did grade 5
I also started the Bach Double at this stage. I loved it and it got me practising, although it must have sounded awful!
Hope that helps.
