Haydn's famous London Sonatas can be viewed as the distillation of the composer's entire sonata-writing experience; Gottlieb perfectly captures his characteristic humour, energy and spiritedness. Sonata No. 60 was written for an instrument of greater tonal range than the Viennese instruments of the day, with a wider palette of specified dynamic possibilities and pedal effects. With a striking two-movement format, asymmetrical phrases and unusual accents Sonata No. 61 was ahead of its time, breaking the limits of traditional sonata form. Often described as a symphony for the piano, Sonata No. 62 has frequently been praised as Haydn's ‘opus summum' due to its large-scale form, diversity of expression and its virtuoso requirements.
