Vivaldi, played badly, is the worst classical music on earth

Vivaldi (the red priest because of his red hair and church duties) was in charge of a church school for "wayward" teenage girls. He composed this and many pieces to keep his girls busy with " proper" instead of banal efforts

I taught the Suzuki method for 40 years.  Its truly the best for study, but thwarts musicality. The music happens between the notes....yes the notes are the foundation, but find your own music. The best edition of the concertos is the Christopher Hogwood edition.  Its not the time you give to your instrument, but the joy you bring to your music.  The violin is just a tool as a carpenter with his hammer.  The perfectly constructed desk, or the joy you bring to Spring in Concerto 1 is the value.
