Pianist Lang Lang's Memory remained at number three.
Among the albums enjoying increased sales this week were Plšcido Domingo's Italia, Ti Amo, a collection of Italian popular songs, which moved from number 13 to number 10 in its third week on the chart. There were no new entries.
The classical-crossover chart was similarly static, with Andrea Bocelli's Amore remaining at number one, followed by Il Divo's Ancora and Il Divo. Amor, the Spanish-language version of Bocelli's album, is still at number four.
The sole new entry was Strung Out On Taking Back Sunday, the latest in a series of string-quartet tributes to rock bands, at number 24.
