"Do I hafta?"
That's the response from legions of pianists who are required to learn mountains of scales, chords, arpeggios. Like oatmeal, technique is supposed to be good for you, but many pianists think that daily doses of it are bland, uninteresting, and merely a preamble to the real business of being a pianist--playing repertoire.
Yet the study of technique is a discipline that can yield much from the fruits of its labor. Here are some of the ways that you can benefit from the regular practice of technique.
1. Learning the building blocks of music. Most Western music is based on a small number of scales and chords. Isolating these elements and making them a part of your daily routine can help you to better understand your repertoire, whether it be classical, pop, rock, jazz, broadway, or country music.
2. Fingering. Humans are equipped with two hands, each of which has a strong second and third fingers, a weak and interdependent fourth finger, a small but spry fifth finger, and an opposable thumb with a completely different manner of operation than the other fingers. Learning the ins and outs of knowing which fingers to use and how can help you tear up and down the keyboard in most spectacular fashion.
3. Sound. Do you actually listen to the sounds you make while practicing those scales and chords? Having a discerning ear for qualities of sound can make those hours become a workout for the ear as well as the fingers.
4. Memorization. The ability to play music from memory is an extremely valuable skill. And where better to learn it than in the workshop of technical exercises and their weird keys, black vs. white notes, fingerings, patterns, and forms.
5. Velocity. Once you're able to slowly and carefully play through a scale, broken chord, or arpeggio, the time is ripe to increase the speed and get through it quicker. I always like to tell students that in order to achieve velocity, they should be thinking faster in addition to playing faster.
6. Warm-up. There is a certain regularity to technical exercises. Many pianists are comforted by having a daily regimen of warm-up exercises that feature technique in order to help them warm up their fingers, hands, wrists, and arms and achieve a sense of grounding at the keyboard before venturing into the minefield of repertoire.
7. Detail. I've lost count of the times I've written that a student's scales were "almost" perfect or "nearly" accurate. Taking that final step to excellence demands hard work and dedication and what better way to get there than by ironing out the details.
8. Focus and Concentration. Everyone says that practicing technique is good for your fingers and overall playing mechanism. That's only part of the story--technique is also a workout for the mind, building mental focus and clarity that can also be put to use no matter what you play.
9. Weird keys. Part of becoming comfortable playing piano is the art of making friends with distant keys. These unlikely friendships (I'm particularly enamored with D flat major) can often spill over into the discovery and enjoyment of new and unexpected corners of the repertoire.
10. Identifying keys. Before you play a technical exercise, it helps a great deal to be able to understand and visualize what it consists of. Dominant and diminished 7ths in particular require some thought as to their layout before embarking upon playing them.
11. Feel the power. What many pianists discover at some time in their development is that playing fast and loud can be incredibly fun. Once you make this discovery, playing technique can be an exercise in power, command, and control of your playing. Rock out, dude.
12. Get those hands playing together. Left vs. right fingering patterns in parallel motion can be entirely different from each other in many scales. And let's not mention that left hands are often more sloppy and inaccurate than right hands. Spending time with the hands apart as well as together can sometimes be a useful fix for this common problem.
13. Keyboard geography. One of my teachers once compared playing piano to sitting in the press box watching a football game. Technique can help you greatly with learning the lay of the land and help you get from end zone to end zone in the heat of battle.
14. Let loose. Practicing technique isn't just about correctness and rigidity, but a lesson in practicing performance as well. Being able to play technique with sparkle and elan is an important step in transforming from student to artist.
15. Evenness and reliability. Above all, a piano technique should be a skill you can rely on and trust, helping you in even the toughest of performance situations with comfort and command.
