The masterclass on performance practice on Érard pianos last sunday the 29th of March was a wonderful happening. I had the great pleasure to work with six very gifted young pianists. They were all students of the Amsterdam Conservatory and had practically no experience with 'authentic' pianos. The repertoire ranged from Mendelssohn to Poulenc and three wonderful Érards were available to us. They were manufactured in 1840,1850 and 1907, all three with parallel strings.
Many topics were covered during the masterclass. Of course there was much attention for the technical intricacies when playing on an Érard. How the different key action (less depth then on a 'modern' piano) and lightness of touch makes one consider more consciously the balance between one's finger action and the armweight. And how the transparency, clarity and natural resonance of the different registers influence the pedalling. Talking about key action, Érards invention of the repetition action made everybody more aware on how to use this wonderful feat whereby you don't need to use the full action of the key once you have pressed it. This made fast repeated notes and tremoli possible(It is no coincidence that both are an intricate part of Liszt's compositions). But it is also directly related to legato playing and there are so many colors as well as technical ease to be found by playing from the middle of the key action and not just from the top of the key. The students realised that this can also be applied to the modern piano that uses the same mechanical principle. With all of them it was marvellous to see how their understanding of the score was put in a new perspective. Slurs, dynamic and pedal markings whether from Mendelssohn, Chopin or Liszt could be performed 'literally' on the period instrument and would always work. In specific parts of the pieces the intention of the composer would suddenly become clearer to them. They realised how the instrument the composer might have used in his time could be a key to understanding his music even better. The question then came up on how to achieve this on the 'modern' piano. One might need more pedal changes and a subtle use of quarter pedal and half pedal. To me this will also broaden one's pianistical scope when these experiences about technique, pedalling and sound are taken to the 'modern' piano. To see all the enthusiasm from the students that came from these learnings was obviously an enormous joy for me. They were all amazed by the relative ease to transition from the Steinway to the Érard. Added to that they were happily surprised by the new ways they could relate to the score thanks to the instrumental possibilities. But the best experience was to see how they loved this different sound unlike anything they were used to until then Even when the masterclass was well over they kept going back to the Érards with their friends to play on them well into the night and be inspired by them.
