The music of Johann Nepomuk Hummel, Mozart’s only full-time student, represents the supreme culmination of the late classical style. The current re-appraisal and appreciation of his music places him as the “missing link” – the logical connection between Mozart, Haydn and Schubert through Chopin to Mendelssohn and Schumann. The Op. 5 Sonatas feature youthful freshness, genial humour and melodic inventiveness. The Luchkow-Jarvis Duo was formed by Paul Luchkow and Michael Jarvis to explore sonata repertoire for violin and keyboard particularly that of the Classical and Romantic periods, on instruments appropriate to each historical period. Paul uses a collection of violins and bows that reflect the changes in construction that took place from the early 17th Century up to the present day and Michael performs on appropriate harpsichords, organs, fortepianos, and early 19th century concert grands (in historical temperaments), bringing audiences closer to the colour, texture and expression the composers knew.
