!! J.S. Bach, WTC Book I; Fugue 19 (3 parts) in A major; BWV 864b
!!
!! NOTE: Voicing in Bach's Fugue 19 (WTC Book I)
!!
!! Between measures 23 and 25 of fugue 19 Bach switches the
!! position of the mid and soprano voices:  the mid-voice climbs up
!! to the higher tessitura and remains there for the remainder of the piece.
!! The soprano(?) voice enters beneath the mid-voice, and continues
!! in the mid-voice tessitura for the remainder of the piece.
!!
!! In this electronic edition, the mid and soprano voices are exchanged
!! in the middle of measure 25.  This preserves both the tessituras
!! of the three spines and avoids the problem of interrupting the subject
!! statement begun at the beginning of measure 25.
