B-flat major

The B♭ (B-flat) major scale consists of the pitches B♭, C, D, E♭, F, G, and A. Its key signature has two flats.

Its relative minor is G minor, and its parallel minor is B♭ minor.

Many transposing instruments are pitched in B-flat major, including the clarinet, trumpet, tenor saxophone, and soprano saxophone. As a result, B-flat major is a popular key for concert band compositions.

History

Joseph Haydn's Symphony No. 98 is credited as the first symphony he (or anyone else) wrote in that key in which he included trumpet and timpani parts. Actually, his brother Michael Haydn had written one such symphony earlier, No. 36, though Joseph Haydn still gets credit for writing the timpani part at actual pitch with an F major key signature (instead of transposing with a C major key signature), a procedure that made sense since he limited that instrument to the tonic and dominant pitches. Many editions of the work, however, use no key signature and specify the instrument as "Timpani in B-flat–F".

String quartet

A string quartet is a musical ensemble of four string players – two violin players, a viola player and a cellist – or a piece written to be performed by such a group. The string quartet is one of the most prominent chamber ensembles in classical music, with most major composers, from the mid to late 18th century onwards, writing string quartets.

The string quartet was developed into its current form by the Austrian composer Joseph Haydn, with his works in the 1750s establishing the genre. Ever since Haydn's day the string quartet has been considered a prestigious form and represents one of the true tests of the composer's art. With four parts to play with, a composer working in anything like the classical key system has enough lines to fashion a full argument, but none to spare for padding. The closely related characters of the four instruments, moreover, while they cover in combination an ample compass of pitch, do not lend themselves to indulgence in purely colouristic effects. Thus, where the composer of symphonies commands the means for textural enrichment beyond the call of his harmonic discourse, and where the concerto medium offers the further resource of personal characterization and drama in the individual-pitted-against-the-mass vein, the writer of string quartets must perforce concentrate on the bare bones of musical logic. Thus, in many ways the string quartet is pre-eminently the dialectical form of instrumental music, the one most naturally suited to the activity of logical disputation and philosophical enquiry.

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.
