Piano sonata

A piano sonata is a sonata written for a solo piano. Piano sonatas are usually written in three or four movements, although some piano sonatas have been written with a single movement (Scarlatti, Scriabin, Medtner), two movements (Haydn), five (Brahms' Third Piano Sonata) or even more movements. The first movement is generally composed in sonata form.

The Baroque keyboard sonata

In the Baroque era, the use of the term "sonata" generally referred to either the sonata da chiesa (church sonata) or sonata da camera (chamber sonata), both of which were sonatas for various instruments (usually one or more violins plus basso continuo). The keyboard sonata was relatively neglected by most composers.

The sonatas of Domenico Scarlatti (of which there are over 500) were the hallmark of the Baroque keyboard sonata, though they were for the most part unpublished during Scarlatti's lifetime. The majority of these sonatas are in one-movement binary form, both sections being in the same tempo and utilizing the same thematic material. These sonatas are prized for both their technical difficulty and their musical and formal ingenuity. The influence of Spanish folk music is evident in Scarlatti's sonatas.

Piano concerto

A piano concerto is a concerto written for a piano accompanied by an orchestra or other large ensemble.

Keyboard concerti were common in the time of Johann Sebastian Bach. Occasionally, Bach's harpsichord concerti are played on piano.

History

In the 17th and 18th centuries, typical concertos for keyboard were organ concertos and harpsichord concertos, such as those written by George Friedrich Handel and Johann Sebastian Bach.

Classical and romantic

As the piano developed and became accepted, composers naturally started writing concerti for it. This happened in the late 18th century, during the Classical music era. Wolfgang Amadeus Mozart was the most important composer in the early development of the form. Mozart's body of masterly piano concerti put his stamp firmly on the genre well into the Romantic era.

Mozart wrote many piano concertos for himself to perform (his 27 piano concertos also include concerti for two and three pianos). With the rise of the piano virtuoso, many composer-pianists did likewise, notably Ludwig van Beethoven, Frédéric Chopin, and Robert Schumann—and also lesser-known musicians like Johann Nepomuk Hummel, Joseph Wölfl, Carl Maria von Weber, John Field, Ferdinand Ries, and F. X. Mozart.

Piano

The piano (Italian pronunciation: [ˈpjaːno]; an abbreviation of pianoforte [pjanoˈfɔrte]) is a musical instrument played using a keyboard. It is widely employed in classical, jazz, traditional and popular music for solo and ensemble performances, accompaniment, and for composing and rehearsal. Although the piano is not portable and often expensive, its versatility and ubiquity have made it one of the world's most familiar musical instruments.

An acoustic piano usually has a protective wooden case surrounding the soundboard and metal strings, and a row of 88 black and white keys (52 white, 36 black). The strings are sounded when the keys are pressed, and silenced when the keys are released. The note can be sustained, even when the keys are released, by the use of pedals.

Pressing a key on the piano's keyboard causes a padded (often with felt) hammer to strike strings. The hammer rebounds, and the strings continue to vibrate at their resonant frequency. These vibrations are transmitted through a bridge to a soundboard that amplifies by more efficiently coupling the acoustic energy to the air. When the key is released, a damper stops the strings' vibration, ending the sound. Although an acoustic piano has strings, it is usually classified as a percussion instrument because the strings are struck rather than plucked (as with a harpsichord or spinet); in the Hornbostel-Sachs system of instrument classification, pianos are considered chordophones. With technological advances, electric, electronic, and digital pianos have also been developed.

Sonata

Sonata (/səˈnɑːtə/; Italian: [soˈnaːta], pl. sonate; from Latin and Italian: sonare, "to sound"), in music, literally means a piece played as opposed to a cantata (Latin and Italian cantare, "to sing"), a piece sung. The term evolved through the history of music, designating a variety of forms until the Classical era, when it took on increasing importance, and is vague. By the early 19th century it came to represent a principle of composing large-scale works. It was applied to most instrumental genres and regarded—alongside the fugue—as one of two fundamental methods of organizing, interpreting and analyzing concert music. Though the musical style of sonatas has changed since the Classical era, most 20th- and 21st-century sonatas still maintain the same structure.

The term sonatina, pl. sonatine, the diminutive form of sonata, is often used for a short or technically easy sonata.

Instrumentation

In the Baroque period, a sonata was for one or more instruments almost always with continuo. After the Baroque period most works designated as sonatas specifically are performed by a solo instrument, most often a keyboard instrument, or by a solo instrument accompanied by a keyboard instrument.

C major

The C major scale consists of the pitches C, D, E, F, G, A, and B. Its key signature has no flats and no sharps.

Its relative minor is A minor and its parallel minor is C minor.

C major is one of the most common key signatures used in western music. Most transposing instruments playing in their home key are notated in C major; for example, a clarinet in B♭ sounding a B-flat major scale is notated as playing a C major scale. The white keys of the piano correspond to the C major scale. Among brass instruments, the contra-bass tuba is in C. A pedal harp tuned to C major has all of its pedals in the middle position.

Simplicity

C major is often thought of as the simplest key, because there are no sharps and no flats, and beginning piano students' first pieces are usually simple ones in this key; the first scales and arpeggios that students learn are also usually C major. However, going against this common practice, the Polish-French composer Frédéric Chopin regarded this scale as the most difficult to play with complete evenness, and he tended to give it last to his students. He regarded B major as the easiest scale to play on the piano, because the position of the black and white notes best fit the natural positions of the fingers, and so he often had students start with this scale. There are no black keys in the C major scale, thus it doesn't fit the natural positions of the fingers well.
