I was looking into the single-beat vs. double-beat historical metronome marks debate, you know, Wim Winters vs. pianopat etc. and I decided to ask Winters a question about Hanon. Here's a copy of my message to Winters:
**********************
Greetings Mr. Winters. I would love to hear your opinions (if any) on Hanon's
Le pianiste virtuose en 60 exercises of 1873, especially since it is another topic which gets people so amusingly bent out of shape. (Georges Mathias approved of Hanon, by the way, and I'm sure you're aware of what Rachmaninoff had to say on the matter.)
Tempo information: Hanon himself states in the Avertissement (Preface), "
On joue entièrement ce volume en une heure [The entire volume can be played in an hour]." This makes it easy to calculate that his metronome markings are single, not double.
Two questions are regularly debated concerning Hanon: One, are the five-finger exercises worthwhile at all, and Two, did Hanon himself intend them to be played in anything other than C major? I am concerned here with this second question.
The publication history is murky. Hanon seems to have initially acted as his own publisher for the first edition of the work in 1873. But on the cover of a 1929 edition, it says:
"Nouvelle Édition revue et augmenteé par Alph. Schotte" [New edition reviewed and augmented by Alphonse Schotte]
"Copyright 1923-1929 by Alph. Schotte & Cie"
"Alph. SCHOTTE & Cie. Successeurs de HANON & DESENCLOS, 1, Impasse Rue de Lille, Boulogne s/ mer."
[IMSLP, and probably everyone else on the planet, has confused this Schotte & Cie with the German publisher Schott. Worse yet, Schott also publishes Hanon -- in the version edited by "Schotte, Alphonse"!]
In this 1929 Alph. Schotte & Cie edition, following Hanon's own Preface, variations on the exercises appear: "
Quelques Variantes proposées pour l'étude du rythme et de l'articulation des doigts et du poignet et que l'on pourra appliquer aux 35 premiers excercices du Pianiste Virtuose. [A few variations, proposed for the study of rhythm and articulation of fingers and wrists, which are to be applied to the first 35 exercises of The Virtuoso Pianist]." 22 rhythmic variations follow.
On the next page we read: "
Quelques autres variantes plus difficiles qui peuvent s'appliquer aux 22 formules précédentes en conservant le doigté d'ut majeur [Some other, more difficult variations, which may be applied to the 22 preceding forms, while conserving the fingering of C major]." Hanon's exercise no. 1 then appears twice; first in C# Major, then in C# Natural Minor.
Did Hanon himself write any of this? Or did Alphonse Schotte add it as part of his 'augmentation'?
Next we read, also on this page: "
Toutes les gammes, les arpèges et les accords de septième en arpèges une fois appris tels qu'ils sont indiqués dans ce cahier, nous conseillons de les étudier avec les rythmes variés ci-après, préconisés par mon vénéré et regretté Maitre, Monsieur Ch. de Bériot, professeur au Conservatoire de Paris [We suggest that all the scales, arpeggios, and seventh-chord arpeggios, once learned according to the instructions in this volume, should be studied with the various rhythms given below, as so strongly recommended by my venerated and much-missed former master, Monsieur Ch. de Bériot, professor at the Paris Conservatory]." More variations follow.
Charles Wilfrid de Bériot became a piano professeur at the Conservatoire in 1887, when Hanon was 68 years old. I think it is most probable, therefore, that all the material after the Avertissement in this 1929 edition was added by Schotte, who was obviously some decades younger than Hanon, and was probably Bériot's student.
These 'variantes' do not appear in the 1900 Schirmer English translation of The Virtuoso Pianist, strengthening my belief that they were the work of Alphonse Schotte.
Unfortunately I do not have access to a copy of the very first (1873) edition of Le Pianiste Virtuose. I am quite confident that Hanon himself proposed no variations of any kind, then or later, but research always results in surprises, no?
**********************
A glance at an original 1873 version would clear up the question completely.
Therefore, until I see other evidence, I conclude that Hanon himself did not propose any rhythmic or key variations on his exercises. It seems that several decades went by until someone first put this suggestion into print, and that first person may have been Alphonse Schotte.
