The item in question is the violin solo half way through Vivaldi's Four Seasons Spring Mov.1. Can anyone please help me understand each bars movement.
The first bar of the solo is an arpeggio fitting the E Major Key scale nicely.
The second bar has an A# not part of the E Major key?
The third bar now has an B# not part of the E Major key!
Is Vivaldi modulating through different keys here? Or is he using modes? Or am I completely off track?
The next few arpeggio bars dropping in pitch fit "E Major" fine, but then there is (I believe) a Tritone in the last bar resolving to C# Minor?
If anyone can please explain this short piece I would be forever grateful!
Many thanks.
