This arrangement of Drei Romanzen für Oboe und Klavier for oboe and chamber orchestra by Rolf Knap, emerged in 1960-1961 in the current form. Haakon Stotijn, solo oboist of the Concertgebouw Orchestra: 'There is a great need for literature for solo oboe and Orchestra literature, especially from the romantic period!'; Cees van der Kraan, co-principal oboist of the Concertgebouw Orchestra: 'Although the piano setting by Schumann is really wonderful; I can imagine that an orchestration of these three romances, if properly done, is scientifically sound.' ; Karel Mengelberg, composer and conductor: 'The three Schumann-romances, also performed with clarinet or violin, lend themselves perfectly as a solo with orchestral accompaniment.' Rolf Knap: 'Now, many years later, I am still convinced that this arrangment credits the intimate nature of this beautiful music of this booksellers son, who lived from 8 June 1810 – 29 July 1856.'

The original sketches of this unfinished work are by Modeste Mussorgsky (1839-1881). Night on the Bare Mountain became known becuase of the orchestral version by Nikolai Rimski-Korsakovs from 1886. The title refers to Russian folklore: on St. John's evening (June 23rd, the longest day or 'midsummer evening'), Tchernobog (Satan) and his witches, sorcerers and evil spirits gather on the Bald Mountain near Kiev.

Zelomaniana means something like 'being diligent tomorrow'. Rolf composed this work for oboe and piano. That original version was performed in the fall of 1976 in the Willem Pijper hall in Rotterdam, during the Gaudeamus competition. Performers were the English oboist John Anderson and his pianist-accompanist. Later on Rolf arranged the work for oboe and string orchestra. As a result, the work gained such a luster that it surpassed the original version. Hence the subtitle 'materiam superabat opus', which means: 'the work surpassed the raw material'. In 1987 Zelomaniana was performed by oboist Hendrik Jan Brethouwer, this performance in the English Church at the Begijnhof in Amsterdam, was broadcast by Radio Amsterdam and the Concertzender. The cadence quoted in the work is by Hendrik Jan. The executive oboist is free to choose this or his own cadence.
