Keyboard concertos by Johann Sebastian Bach

The harpsichord concertos, BWV 1052–1065, are concertos for harpsichord, strings and continuo by Johann Sebastian Bach. There are seven complete concertos for a single harpsichord (BWV 1052–1058), three concertos for two harpsichords (BWV 1060–1062), two concertos for three harpsichords (BWV 1063 and 1064), and one concerto for four harpsichords (BWV 1065). Two other concertos include solo harpsichord parts: the concerto BWV 1044, which has solo parts for harpsichord, violin and flute, and Brandenburg Concerto No. 5 in D major, with the same scoring. In addition there is a nine-bar concerto fragment for harpsichord (BWV 1059) which adds an oboe to the strings and continuo.

Most of Bach's harpsichord concertos (with the exception of the 5th Brandenburg Concerto) are thought to be arrangements made from earlier concertos for melodic instruments probably written in Köthen. In many cases, only the harpsichord version has survived. They are among the first concertos for keyboard instrument ever written

Concerto in F (Gershwin)

Concerto in F is a composition by George Gershwin for solo piano and orchestra which is closer in form to a traditional concerto than the earlier jazz-influenced Rhapsody in Blue. It was written in 1925 on a commission from the conductor and director Walter Damrosch.

Genesis of the Concerto

Damrosch had been present at the February 12, 1924 concert arranged and conducted by Paul Whiteman at Aeolian Hall in New York City titled An Experiment in Modern Music which became famous for the premiere of Gershwin's Rhapsody in Blue, in which the composer performed the piano solo. The day after the concert, Damrosch contacted Gershwin to commission from him a full-scale piano concerto for the New York Symphony Orchestra, closer in form to a classical concerto and orchestrated by the composer.

Harpsichord concerto

A harpsichord concerto is a piece of music for an orchestra with the harpsichord in a solo role (though for another sense, see below). Sometimes these works are played on the modern piano (see piano concerto). For a period in the late 18th century, Joseph Haydn and Thomas Arne wrote concertos that could be played interchangeably on harpsichord, fortepiano, and (in some cases) pipe organ.

The Baroque harpsichord concerto

The harpsichord was a common instrument, but never as popular as string or wind instruments in the concerto role, probably due to its relative lack of volume in an orchestral setting. In this context, harpsichords were more usually employed as a continuo instrument, playing a harmonised bass part in nearly all orchestral music, the player often also directing the orchestra.

Bach's Brandenburg Concerto No.5 in D major, BWV 1050, may be the first work in which the harpsichord appears as a concerto soloist. In this piece, its usual continuo role is alternated with prominent solo obbligato episodes in all three movements. In the first movement the harpsichord, after rapid scales up and down the length of its range, embarks on a solo cadenza which lasts for 3–4 minutes, while the orchestra is silent.

F minor

F minor is a minor scale based on F, consisting of the pitches F, G, A♭, B♭, C, D♭, and E♭. The harmonic minor raises the E♭ to E♮. Its key signature has four flats.

Its relative major is A-flat major, and its parallel major is F major.

Two famous pieces in the key of F minor are Beethoven's Appassionata Sonata, and Haydn's Symphony No. 49 in F minor, La Passione.

Glenn Gould once said if he could be any key, he would be F minor, because "it's rather dour, halfway between complex and stable, between upright and lascivious, between gray and highly tinted...There is a certain obliqueness."

Notable compositions

Concerto

A concerto (from the Italian: concerto, plural concerti or, often, the anglicised form concertos) is a musical composition, whose characteristics have changed over time. In the 17th century, "sacred works for voices and orchestra were typically called concertos." J. S. Bach "was thus reflecting a long-standing tradition when he used the title `concerto' for many of the works that we know as cantatas.". But in recent centuries, up to the present, a concerto is a piece usually composed in three parts or movements, in which (usually) one solo instrument (for instance, a piano, violin, cello or flute) is accompanied by an orchestra or concert band.

The etymology is uncertain, but the word seems to have originated from the conjunction of the two Latin words conserere (meaning to tie, to join, to weave) and certamen (competition, fight): the idea is that the two parts in a concerto, the soloist and the orchestra or concert band, alternate episodes of opposition, cooperation, and independence in the creation of the music flow.
