1 (number)

1 (one; /ˈwʌn/ or UK /ˈwɒn/, also called unit, unity, and (multiplicative) identity), is a number, a numeral, and the name of the glyph representing that number. It represents a single entity, the unit of counting or measurement. For example, a line segment of unit length is a line segment of length 1.

As a number

One, sometimes referred to as unity, is the integer before two and after zero. One is the first non-zero number in the natural numbers as well as the first odd number in the natural numbers.

Any number multiplied by one is that number, as one is the identity for multiplication. As a result, one is its own factorial, its own square, its own cube, and so on. One is also the result of the empty product, as any number multiplied by one is itself. It is also the only natural number that is neither composite nor prime with respect to division, but instead considered a unit.

As a digit

The glyph used today in the Western world to represent the number 1, a vertical line, often with a serif at the top and sometimes a short horizontal line at the bottom, traces its roots back to the Indians, who wrote 1 as a horizontal line, much like the Chinese character 一. The Gupta wrote it as a curved line, and the Nagari sometimes added a small circle on the left (rotated a quarter turn to the right, this 9-look-alike became the present day numeral 1 in the Gujarati and Punjabi scripts). The Nepali also rotated it to the right but kept the circle small. This eventually became the top serif in the modern numeral, but the occasional short horizontal line at the bottom probably originates from similarity with the Roman numeral I. In some countries, the little serif at the top is sometimes extended into a long upstroke, sometimes as long as the vertical line, which can lead to confusion with the glyph for seven in other countries. Where the 1 is written with a long upstroke, the number 7 has a horizontal stroke through the vertical line.

Ballades (Chopin)

Frédéric Chopin's four ballades are one-movement pieces for solo piano, composed between 1831 and 1842. They are some of the most challenging pieces in the standard piano repertoire.

The term ballade was used by Chopin in the sense of a balletic interlude or dance-piece, equivalent to the old Italian ballata, but the term may also have connotations of the medieval heroic ballad, a narrative minstrel-song, often of a fantastical character. There are dramatic and dance-like elements in Chopin's use of the genre, and he may be said to be a pioneer of the ballade as an abstract musical form. The four ballades are said to have been inspired by poet Adam Mickiewicz. The exact inspiration for each individual ballade, however, is unclear and disputed.

The ballades are considered an innovation of Chopin's and cannot be placed into another form (e.g. sonata). Though they do not conform exactly to sonata form, the "ballade form" created by Chopin for his four ballades is a distinct variant of sonata form with specific discrepancies, such as the mirror reprise (presenting the two expositional themes in reverse order during the recapitulation). The ballades have directly influenced composers such as Franz Liszt and Johannes Brahms who, after Chopin, wrote ballades of their own.

G minor

G minor is a minor scale based on G, consisting of the pitches G, A, B♭, C, D, E♭, and F. For the harmonic minor scale, the F is raised to F♯. Its relative major is B-flat major, and its parallel major is G major.

Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. G minor is one of two flat key signatures that require a sharp for the leading-tone (the other is D minor).

Mozart's use of G minor

G minor has been considered the key through which Wolfgang Amadeus Mozart best expressed sadness and tragedy, and many of his minor key works are in G minor, such as the Piano Quartet No. 1 and the String Quintet in G minor. Though Mozart touched on various minor keys in his symphonies, G minor is the only minor key he used as a main key for his numbered symphonies (No. 25, and the famous No. 40). In the Classical period, symphonies in G minor almost always used four horns, two in G and two in B-flat alto. Another convention of G minor symphonies observed in Mozart's No. 25 was the choice of E-flat major for the slow movement, with other examples including Haydn's No. 39 and Johann Baptist Wanhal's G minor symphony from before 1771 (Bryan Gm1).
