Isometric Rhythmic Practice

My organ and piano practicing is based on modified rhythms, which I described here and here, and demonstrated on YouTube here.

Today I learned a name for it: Isometric Rhythmic Practicing. The magazine International Piano’s regular column “Key Notes” by Murray McClachlan is an excellent focus on one or another aspect of piano technique, which of course applies to organ as well. In the current issue’s column, “Clarity,” McClachlan writes:
One of the most common methods for developing clear, strong articulation which many tutors have traditionally recommended over generations of pedagogy is ‘isometric rhythmic’ practicing… (International Piano, Nov.-Dec. 2018, p. 49)
McClachlan then describes the method, with an example from a Bach WTC prelude.

Armed with a name, I eagerly launched a DuckDuckGo search for “isometric rhythmic practicing” and found… almost nothing. References to isometric rhythm as a medieval compositional principle. Medical references of various sorts. Lots of references to Harold Blomberg’s “Rhythmic Movement Training.” Further down the list, materials about Rhythmic Gymnastics. Keyboard practicing references? Nope, though I found one reference to guitar finger exercises.

The name was not as useful as I had hoped. And if this method is so common as to be traditional “over many generations of pedagogy,” why is it that I have never overheard anyone else practicing this way, other than one of my students?

But in some further looking around, I turned up this: www.pianopractice.org

It is a web page maintained by Chuan C. Chang, which includes a link to a free download of his 300-plus page PDF book, “Fundamentals of Piano Practice.” His approach, based on the teaching of Yvonne Combe and behind that, her training at the Paris Conservatory in the early twentieth century, is not the same as isometric rhythms, but he does discuss “segmental practice” as an aid to overcoming what he calls “speed walls,” which are “conditions in which you can’t go above a certain speed, no matter how hard you practice. SW [speed walls] form when you practice incorrectly and create bad habits or build up stress” (p. 29). Segmental practice is helpful “because the shorter a segment, the faster you can play it without problems.” The shortest segment is two notes, and that is the basis of isorhythmic practice. If you can play a two-note group quickly and with ease, you can extend that to four-note groups and beyond.

Chang’s book looks to be fascinating. Besides the material on piano practice, he devotes space to choosing a piano [he shares my views concerning the digital pianos and their superiority over acoustic uprights, but not over the best of the acoustic grand pianos: pp. 184-195], and tuning your own piano, including discussion of historic temperaments. He recommends Kirnberger II for the beginning tuner because it is easier than equal temperament, and he notes that “once you get used to K-II, ET [equal temperament] will sound a little lacking or ‘muddy.’” (p. 227). He gives the “recipe” for Kirnberger II on page 228. Chang concludes with a long and well-annotated bibliography for further study.

I am going to enjoy reading this book.

[Edited 12/5/18 to add: Chang briefly dismisses my practice method as follows: "The literature lists numerous methods for improving technique such as the rhythm method (change the rhythm or accented note), tapping, etc. The biggest drawback with such methods is that they waste time because there are too many rhythms, etc., that you need to practice." (p. 58)

As expected, I am thoroughly enjoying the book. I disagree with quite a bit of what he writes, but have taken a few ideas from it, notably a reminder of how helpful it can be to practice short segments hands separately. Some of my disagreements stem from differences between playing the organ and the piano, and the literature for the respective instruments. Practice techniques that would be helpful for Chopin, Liszt, Rachmaninoff might be less useful for Bach and Buxtehude, and the coordination issues that one dodges by hands-separate practice are increased when one adds feet as well as hands, so (in my opinion) an organist needs much more work with hands/feet together than would a pianist.

I thoroughly agree with what he states is the thesis of the book: "If you don't make any progress [on a new piece being learned, or a specifically difficult passage] after a few days... it is time to stop and think of new things to do... if you don't make progress, you are doing something wrong -- that is the basic principle of this book." (p. 51-52)]

Unrelated Afterword: Fear of Red Ink

I have been listening to some of my older organ and piano improvisations recently. Some are horrible; some are not so bad. But one thought that these improvisations provoked is worth mentioning, because I think it is a major obstacle to the musician who wants to improvise. I call it the “Fear of Red Ink.”

Back in undergraduate theory class, my harmony exercises were returned with lots of red ink, marking my mistakes. Lots of them. Dozens on every page. All circled in red ink, often with caustic remarks from the teacher (likewise in red ink). Most of them were parallel octaves and fifths which had entirely escaped my scrutiny in writing the exercises. Parallel octaves and fifths are Against the Rules, and rightly so in pre-twentieth century styles. The rule goes back at least to Fux’s Gradus ad Parnassum, which I revere, though we were not told that in beginning theory.

So, the pianist launches into an improvisation. Before the first phrase is done, a parallel fifth appears. The improviser stops, horrified that he has committed such a sin. He is more careful the next time, but this time a parallel octave shows up. Fear of Red Ink ensues, with painful memories of those first-year harmony exercises. The would-be improviser is likely to say “I can’t do this,” and gives up.

But with the broadening of horizons brought by harmonic and post-harmonic developments in the twentieth century comes greater freedom in the use of parallels. Vaughan Williams is filled with parallel fifths; it is a hallmark of his style.

So, my rule of thumb:
Ignore the Red Ink.
You can notice parallelisms when they happen, and if you wish, seek to do less of them, for in many styles they do genuinely weaken the contrapuntal structure. But you must not let them stop you or derail your improvised composition. You must press on.

One little trick that I use: when I accidentally play a parallel octave, I might turn it into the beginning of a passage in parallel octaves, doubling the melody an octave below, and similarly with fifths. Even though the initial parallelism was accidental, it sounds more or less like I planned it that way.

Cheating? Probably. But you must press on.
