I have always enjoyed Baroque music and Antonio Vivaldi the "Red Priest" my favorite baroque composer can be frequently heard among the flora.
Here is a list of some works I enjoy in the garden. I often lay on my back surrounded by the verge, turn vision skyward and open my mind to the music.
Chamber Concerto in G minor, (RV 107)
Concerto for Strings and Basso Continuo in D minor, (RV 128)
Trio for Violin, Lute & Cello in G minor, (RV 85)
