In the car on the way to and from work:
Mendelssohn - String Quintet Op.18
Mendelssohn - Overtures: Hebrides, Fair Melusine, Midsummer Night's Dream, Calm Sea & Prosperous Voyage
While out at work Christmas Lunch:
Pachelbel - Canon
Mozart - Slow Movement from Piano Concerto No.21
Brahms - Bits of St Antoni Variations
Vivaldi - "Spring" from the 4 Seasons
Adolphe Adam - O Holy Night
Handel - Hallelujah Chorus
At home in the evening:
Saint Saens - Symphony in A Major, Symphonies No.1 & No.2
Beethoven - Violin Sonatas "Spring" and "Kreutzer"
Comment: there was other music going on during lunch, but sometimes the noise of people chattering was too loud for me to hear the music. The bits I heard were (a) before too many people had arrived and (b) while food was there and people were too busy eating to chat!
