Investigating the Inventions

I'm hearing lots of work on the Bach Two-Part Inventions at WBU lately. These are great works to introduce pianists to the finer points of Baroque style while working on independence of hands. They also serve as a perfect entryway to the preludes and fugues of the Well Tempered Clavier. However, young pianists can find them extremely challenging because of the counterpoint. While my colleague was away last week, I found myself offering advice to freshmen preparing these works and a few points seemed to come up repeatedly.

• Slow and steady practice is necessary. Young pianists often want to attempt to play at top speed from the beginning. This is never advisable, but it is certainly not going to produce success when studying Bach.
• There is great value in practicing each hand separately. Because these works become very complex very quickly, it is useful to work on one hand at a time. While doing so, it is important to also.....
• Be meticulous! Make sure that you are playing accidentals throughout the entire measure. Analyze rhythmic patterns carefully and demand accuracy from the start. Settle on good fingering patterns early in the process and don't forget to address articulation as well. Don't fool yourself into thinking you will remember all of your choices either -- take the time to mark your score (possibly in a colored pencil!) as you are working. It may be tedious work now, but you will be thankful for it later.
• When putting hands together, work from one strong beat to the next. Fewer things can be more frustrating and discouraging than attempting to play a long passage in an Invention when things simply are not going well. Shorten the length of the passage -- maybe to a few beats or a single measure -- as you are putting both lines together. This increases the chance for success and highlights technical patterns that may exist between the hands. Personally, I find that working from the beginning of the measure to the next downbeat -- crossing the bar line -- helps me fix problems while maintaining a constant sense of rhythmic propulsion.
• Ruthlessly fight for steady rhythms! Students often get into the habit of inserting hesitations into the polyphonic writing. The thought is that note accuracy is most important and that rhythmic accuracy can come later. Unfortunately, these pauses in the musical line quickly become set in muscle memory and are extremely hard to correct later. Instead of hesitating, slow things down and play the invention only as fast as you can play with both note and rhythmic accuracy.
• Inventions are all about SHAPE! The Inventions are often approached as technical exercises. These charming works are musical gems! As you are perfecting the notes and polishing rhythms, don't lose sight of the music. Listen for the rise and fall of the line. Notice how the two voices play off of each other, creating a sparkling dialogue. As you find the music, the Inventions will become much more exciting to study, causing you to spend more time with the work rather than dreading more time trying to fix the problems. Simply put, let the two voices sing and enjoy the melody.
