Trills

There is no better demonstration of the effectiveness of the parallel set exercises (chord attack) than using them to learn the trill. There are only two problems to solve in order to trill: (1) speed (with control) and (2) to continue it as long as desired. The parallel set exercises were designed to solve exactly these problems and therefore work very well for practicing trills. Whiteside describes a method for practicing the trill which, upon analysis, turns out to be a type of chord attack. Thus use of the chord attack for practicing the trill is nothing new. However, because we now understand the learning mechanism in more detail, we can design the most direct and effective approach by using parallel sets. The first problem to solve is the initial two notes. If the first two notes are not started properly, learning the trill becomes a very difficult task. The importance of the first two notes applies to runs, arpeggios, etc., also. But the solution is almost trivial -- apply the two note parallel set exercise. Therefore, for a 2323.... trill, use the first 3 as the conjunction and get the first two notes right. Then practice the 32, then 232, etc. It's that simple! Try it! It works like magic! Don’t just concentrate of parallel sets and speed because that will usually be insufficient. You must try different hand motions, such as quiet hands, flat finger positions (see 4.b below), etc. Relaxation is even more critical for the trill than almost any other technique because of the need for rapid momentum balance; that is, the parallel sets, being only two notes, are too short for us to rely solely on parallelism to attain speed. Thus we must be able to change the momenta of the fingers rapidly. Stress will lock the fingers to the larger members such as palms and hands, thus increasing the effective mass of the fingers. Larger mass means slower motion: witness the fact that the hummingbird can flap its wings faster than the condor and small insects even faster than the hummingbird. This is true even if the air resistance were ignored; in fact, the air is effectively more viscous to the hummingbird than to the condor and for a small insect, the air is almost as viscous as water is to a big fish. It is therefore important to incorporate complete relaxation into the trill from the very beginning, thus freeing the fingers from the hand. Trill is one skill that requires constant maintenance. If you want to be a good triller, you will need to practice trilling every day. The chord attack is the best procedure for keeping the trill in top shape, especially if you had not used it for a while and feel like you might be losing it, or if you want to continue improving it. Finally, the trill is not a series of staccatos. The fingertips must be at the bottom of the keydrop as long as possible; i.e., the backchecks must be engaged for every note. Take careful note of the minimum lift necessary for the repetition to work. Those who practice on grands should be aware that this lift distance can be about twice as high for an upright. Faster trills require smaller lifts; therefore, on an upright, you may have to slow down the trill.
