Invention No. 14 in B flat major
B-flat major - a melody that remembers it was once a song.
Invention No. 14 in B-flat major is the most overtly melodic piece in the Clavier-Büchlein - its opening right-hand phrase has the contour and breath of a vocal aria rather than a keyboard exercise. B-flat major, warm and rounded in tone on both harpsichord and clavichord, suited the kind of singing keyboard writing that Bach associated with the Italian style he had studied closely in his youth, transcribing concertos by Vivaldi and Albinoni to understand how melodic lines were sustained over supporting harmonic motion.
The contrapuntal structure here is more relaxed than in the tightest of the Inventions: the left hand provides a walking bass and occasional imitative entries, but its primary role is harmonic support for the melody above. This makes No. 14 an ideal piece for practicing the most fundamental skill of all two-voice keyboard writing: keeping a singing upper voice audible and shaped above a steady, unobtrusive lower voice - something far harder to achieve than any amount of imitative counterpoint.
Shape the melody as if writing for voice.
Sing the right-hand melody before playing it and notice where the natural peaks and resting points fall - those are the dynamic contours the fingers should reproduce. When practicing hands separately, make the right-hand phrase as expressive as possible on its own; it should feel complete even without the left hand. When combining, the left hand should recede dynamically to roughly half the right-hand volume so the melody always speaks clearly above it.
Before you practice.
01 Is Bach Invention No. 14 appropriate for late beginners?
Yes, although its tight imitative structure is more demanding than the earlier inventions. Students who have already practiced Nos. 1-7 will find the two-flat B-flat key manageable while the closer voice entries provide a genuine new challenge.
02 How many bars is BWV 785?
Invention No. 14 in B-flat major is only 20 bars long, making it one of the shorter pieces in the set. Its brevity is deceptive - the density of the imitation means every bar requires careful attention.
Balance: melody above, bass below.
At 50% tempo, practice adjusting the touch so the right hand is consistently louder than the left - this is a physical habit that requires deliberate cultivation. Use the loop feature on the opening eight-measure melody to work on its expressive arc before moving to the middle section. At 75% tempo the melodic quality should be fully present. Wait-for-note is off; focus on tone quality at whichever tempo you choose.
