What Were The Specific Modifications Made By Theodore Steinway To The 1866 Steinway Model D That Allowed Franz Liszt To Achieve The Desired Tonal Resonance And Sustain During His Performances Of The La Campanella Etude, And How Did Those Modifications Influence The Subsequent Design Of The Steinway Model A?
Theodore Steinway's modifications to the 1866 Model D were crucial in enhancing the piano's performance, particularly for demanding pieces like Franz Liszt's La Campanella etude. Key modifications included:
-
Action improvements: Theodore likely enhanced the action mechanism for faster repetition and better control, crucial for intricate passages. Adjustments to the balance rail and hammer felts improved responsiveness and efficiency.
-
String scaling: Modifications in string length, tension, or material improved tone and sustain, contributing to the bell-like clarity required for La Campanella.
-
Soundboard design: Changes in soundboard thickness or material enhanced resonance and projection, allowing the piano to produce the desired tonal quality.
-
Technological innovations: Possible inclusion of new patents, such as the sostenuto pedal, which helped in sustaining specific notes without blurring, adding to the expressive capabilities.
These innovations influenced the subsequent design of the Steinway Model A, which became known for its versatility and balance between power and expressiveness. The Model A incorporated improved action mechanisms, string scaling, and soundboard designs, reflecting the advancements from the Model D.
