This is J.S. Bach’s transcription of the first movement from A. Marcello’s oboe concerto. Bach was a great copier of music making it suitable for performance on the organ. Bach’s version dates from 1715. The score is marked Andante spiccato. Spiccato is a reference to a type of staccato and bowing technique on a string instrument. There is much to be learnt about the baroque concerto playing this movement and the terms frequently associated with the music all have a context. Tutti (all) ritornello (a recurring passage / theme / refrain) ripieno (whole group) concertino (solo group) episode (a musical section or passage that is not the theme). A competent performance of this movement should demonstrate that the player has a clear understanding of both the structure and texture. Remember that Bach’s keyboard transcription was originally an orchestral work. Ornaments featured in the movement are presented simply and consistently. Keyboard players will find many variants in terms of their frequency and their interpretation. Listen to recordings and copy the best of modern practice is the best advice. When learning the piece the music editor suggests omitting the ornaments. The ornaments have been written out in the piano video score available to view on our YouTube channel (the same ornaments feature in both the piano and organ sheet music scores). The organ sheet music score available from the PlentyMusic website has the symbols for the ornaments in place which understandably gives the score visual clarity. The organ realisation plays back at 72 quarter note (crotchet) beats to the minute. Clarity in the articulation of every note is the challenge in playing the music of J. S. Bach. As is the custom with the notation of baroque music there is very little score detail but understandably as the piano invites dynamic shading there is scope for interpretation and nuance in a performance. The movement ends with a Tierce de Picardy aka a Picardy third. This is essentially refers to the use of a major chord at the end of a piece in the minor key.
