Music Reviews New Pedagogical Works by Callus, Slapin, and Vamos Katrin Meidell

When tasked with writing a review of new scale and etude books, I rolled my eyes and thought, “MORE scale books? What can someone possibly write that hasn’t already been covered by Galamian, Flesch, Primrose, and the rest?” But when the books arrived in the mail, I was surprised by what greeted me. Making perhaps the most positive impression was Helen Callus’ One-Step Scale System for Viola: 10 Exercises to a Better Left Hand . Of the etude books, I was impressed with Scott Slapin’s 24 Progressive Etude s for viola solo or duo, and delighted to learn that Roland Vamos had finally published his impressive Exercises for the Violin in Various Combinations of Double-Stops for viola (both violin and viola versions published by Carl Fischer). I’ve been using the violin version of Vamos’s work for years with much success (after quite a bit of frustration) with my students. Now that the exercises have been transposed down a fifth, I highly encourage the swift acquisition of this etude book. The double-stops are quite difficult at first, and get to the heart of a common problem among less-developed violists—true independence of fingers. Vamos methodically trains the left hand across positions through combinations of double stops that you won’t necessarily find in wide use in repertoire. These double stops solidly center the hand within each position, training intonation based on the octave and stable hand frame, as well as dexterity and independence of fingers. I highly encourage my students to use as little hand strength as possible, as the exercises can lead to tightness and squeezing if not vigilant about easing unnecessary tension. I also come from the school of thought where no excess fingers should be left on the fingerboard, so ask my students to lift their fingers such that there are only ever two fingers on the fingerboard at a time (Vamos himself marks this in versions H and I of each position and pattern). This is where finger

independence truly is learned, and it helps students release tension that otherwise can build in the hand.

Slapin’s charming 24 Progressive Etudes for viola solo or duo, published by Ourtext, is another fine addition to etude repertoire. Published in three parts, Book I, Book II, and Score, the etudes can either be learned individually or as a duet. I enjoyed recording myself and then playing the corresponding etude with my recording (e.g. No. 1, the first in Book I, and No. 13, the first in Book II, are a duet, as are Nos. 2 and 14, etc.). The first set of etudes are in first position. No. 1, which is a series of eighth notes, doesn’t always go where you’d expect, and when I asked two students to sight read the etudes, they fell into the holes Slapin so craftily composed. In addition to unexpected leaps and harmonic changes, the meter changes occasionally. These etude sets encourage active reading and require the brain to be “on” for correct execution. Furthermore, you can perform with your student, which is always fun. Likewise, they truly are progressive, with each etude set becoming more difficult. The final set, Nos. 12 and 24, changes keys every two measures for nearly the entire etude, but again, doesn’t always go where you’d expect. While No. 12 stays in alto clef, No. 24 utilizes quite a bit of treble clef. The etudes would make a fine addition to the library of any private teacher, and I estimate they would be a nice precursor to the early Kreutzer etudes. They would be especially appropriate to use with students switching from violin, because they were composed for the viola and there’s no chance the student played them in their former life as a violinist. Hellen Callus’s One-Step Scale System for Viola: 10 Exercises to a Better Left Hand is an excellent addition to the otherwise highly-saturated scale book market. In the preface, Callus writes, “The objective with this
