"Air on a G String" is taken from the second movement of Johan Sebastian Bach's orchestral suite No 3 in D major. I have arranged it in A because it feels, sits and sounds right to my ear. The piano accompaniment is no more than intermediate.

This is an accurate arrangement of "Domestic Pressures" for violin and piano.
This piece is from the soundtrack to the 2014 movie The Theory of Everything.
The score and the individual parts are included (10 pages).

The Theory of Everything is a biographical romantic drama film directed by James Marsh. Set at the University of Cambridge, it details the life of the theoretical physicist Stephen Hawking.
At the 87th Academy Awards, it was nominated in the categories of Best Original Score for J�hann J�hannsson.

The traditional Canon In D of Johann Pachelbel here Violin and Piano version, In this arrangement both parts are musical and fun to play, the entire arrangement keeps the essence of the original composition but some variations were added. Lyricism, lovely beauty and solemnity are the words that describe this piece, 3:20 minutes long approx, intermediate level, special for weddings, recitals, concerts, Valentine's Day and any events.
