B-flat major is a major scale based on B♭, with 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-flat minor. The B-flat major scale is: Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The B-flat harmonic major and melodic major scales are: 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 one of the most popular keys for concert band compositions.

Luigi Boccherini's Cello Concerto No. 9 in B-flat Major, G. 482, was written in either the late 1760s or early 1770s. Boccherini, a talented cellist, composed twelve concertos for his instrument. In 1895 German cellist Friedrich Grützmacher chose this concerto to be arranged to fit the style of a Romantic virtuoso concerto, and in this form, widely heard, it bears only a tenuous resemblance to the original manuscript. The Boccherini Ninth Cello Concerto has long been an integral part of standard cello instruction, because of creeping use of the full 4+ octave range of the cello, rather than large jumps between different finger positions. Grützmacher merged Boccherini's Ninth Cello Concerto with other Boccherini Cello Concertos. Besides the extensive cuts in the outer movements, Grützmacher decided to rid the Concerto of its original second movement, replacing it with that of the Seventh Cello Concerto (in G Major, G.480). The Fourth Cello Concerto (In C Major, G.477) makes an appearance in bars 40-46 of the first movement, and in bars 85-96 and 151-163 of the Rondo, borrowing from the respective movements. The arpeggios of the Fifth Cello Concerto's (in D Major, G478) first movement are featured in their minor form in bars 47-53 of the first movement. Grützmacher also took the liberty of writing his own cadenzas. Despite all the changes, this Concerto holds up as one of Boccherini's best-known works. Pablo Casals, Pierre Fournier, Janos Starker, and Jacqueline du Pré all made recordings of the Grützmacher version of the Concerto. Maurice Gendron and Yo-Yo Ma have made recordings of the original work. The two works are distinguished by their origin: Original vs. arr. Grützmacher.

A cello concerto (sometimes called a violoncello concerto) is a concerto for solo cello with orchestra or, very occasionally, smaller groups of instruments. These pieces have been written since the Baroque era if not earlier. However, unlike instruments such as the violin, the cello had to face harsh competition from the older, well-established viola da gamba. As a result, few important cello concertos were written before the 19th century – with the notable exceptions of those by Vivaldi, C.P.E. Bach, Haydn and Boccherini. Its full recognition as a solo instrument came during the Romantic era with the concertos of Schumann, Saint-Saëns, Lalo and Dvořák. From then on, cello concertos have become more and more frequent. Twentieth-century composers have made the cello a standard concerto instrument, along with the already-rooted piano and violin concertos; among the most notable concertos of the first half of the century are those of Elgar, Prokofiev, Barber and Hindemith. Many post-World War II composers (Shostakovich, Walton, Ligeti, Britten, Dutilleux, Lutoslawski and Penderecki among others) have written at least one. One special consideration composers must take with the cello (as well as all instruments with a low range) is with the issue of projection. Unlike instruments like the violin, whose high range projects fairly easily above the orchestra, the cello's lower notes can be easily lost when the cello is not playing a solo or near solo. Because of this, composers have had to deliberately pare down the orchestral component of cello concertos while the cello is playing in the lower registers.

Ridolfo Luigi Boccherini (, also US: ; Italian: [riˈdɔlfo luˈiːdʒi bokkeˈriːni] ; 19 February 1743 – 28 May 1805) was an Italian composer and cellist of the Classical era whose music retained a courtly and galante style even while he matured somewhat apart from the major classical musical centers. He is best known for a minuet from his String Quintet in E, Op. 11, No. 5 (G 275), and the Cello Concerto in B flat major (G 482). The latter work was long known in the heavily altered version by German cellist and prolific arranger Friedrich Grützmacher, but has recently been restored to its original version. He is also particularly well known for his Night Music of the Streets of Madrid, Musica notturna delle strade di Madrid. Boccherini's output also includes several guitar quintets. The final movement of the Guitar Quintet No. 4 in D (G 448) is a fandango, a lively Spanish dance.
