Thanks to Bach Musica's indefatigable director, Rita Paczian, the group's Journey to Salzburg and Vienna treated a reasonably large audience to a first-class musical trip on Sunday.
The opening Mozart Sinfonia Concertante must be one of the composer's most personal works (Mozart probably played the viola part at the first performance in 1779).
Its opening Allegro is as graceful a maestoso as one could wish for and the lyricism of the central Andante almost melts on the page.
Violinist Sarah McCracken and violist Julia Joyce were extremely responsive to the special partnership that this score gives them. If McCracken was occasionally pinched in tone, then Joyce more than compensated with tonal warmth and generosity, drawing her colleague into some shapely duetting.
The Holy Trinity acoustics are not flattering at the best of times and on this occasion they conspired to thicken the texture.
