Number

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, and so forth. A notational symbol that represents a number is called a numeral. In addition to their use in counting and measuring, numerals are often used for labels (as with telephone numbers), for ordering (as with serial numbers), and for codes (as with ISBNs). In common usage, the term number may refer to a symbol, a word, or a mathematical abstraction.

In mathematics, the notion of number has been extended over the centuries to include 0, negative numbers, rational numbers such as and , real numbers such as and , complex numbers, which extend the real numbers by including , and sometimes additional objects. Calculations with numbers are done with arithmetical operations, the most familiar being addition, subtraction, multiplication, division, and exponentiation. Their study or usage is called arithmetic. The same term may also refer to number theory, the study of the properties of the natural numbers.

Nursery rhyme

A nursery rhyme is a traditional poem or song for young children in Britain and many other countries, but usage only dates from the late 18th /early 19th century. In North America the term Mother Goose Rhymes, introduced in the mid-18th century, is still often used.

History

Lullabies

The oldest children's songs of which we have records are lullabies, intended to help a child sleep. Lullabies can be found in every human culture. The English term lullaby is thought to come from "lu, lu" or "la la" sound made by mothers or nurses to calm children, and "by by" or "bye bye", either another lulling sound, or a term for good night. Until the modern era lullabies were usually only recorded incidentally in written sources. The Roman nurses' lullaby, "Lalla, Lalla, Lalla, aut dormi, aut lacta", is recorded in a scholium on Persius and may be the oldest to survive.

Many medieval English verses associated with the birth of Jesus take the form of a lullaby, including "Lullay, my liking, my dere son, my sweting" and may be versions of contemporary lullabies. However, most of those used today date from the 17th century. For example, a well known lullaby such as "Rock-a-bye, baby on a tree top", cannot be found in records until the late-18th century when it was printed by John Newbery (c. 1765).

And I

"And I" is a song written by American R&B singer Ciara, and produced by Adonis Shropshire for Ciara's first album, Goodies (2004). It was released as the album's fourth and final single on August 30, 2005 (see 2005 in music) in North America.

The song was originally the third choice for the fourth single. Ciara has mentioned in an interview that "Thug Style", "Hotline" or "Pick up the Phone" would be the fourth single, but when Ciara suggested "And I" to executives at her previous record label LaFace, they were unhappy because they wanted "Next to You" to be the fourth single.

Chart performance

At the time of the U.S. release of "And I", Ciara's collaboration with Bow Wow, "Like You", and her collaboration with Missy Elliott, "Lose Control", were at the height of their popularity. "And I" peaked at 96 on the U.S. Billboard Hot 100 and 27 on Billboard's Hot R&B/Hip-Hop Singles & Tracks chart, which were poor positions compared to those attained by the first three singles from the album Goodies. It was not released outside North America because of this, and it is Ciara's least successful single.

Your Number is the eleventh Japanese single by South Korean boy group Shinee. The single was released on March 11, 2015 by Universal Music Japan sublabel EMI Records.

For Children (Bartók)

For Children (Hungarian: A Gyermekeknek) is a cycle of short piano pieces composed by Béla Bartók. The collection was originally started in 1908 and completed in 1909, and comprised 85 pieces which were issued in four volumes. Each piece is based on a folk tune, Hungarian in the first two volumes (42 pieces), and Slovakian in the last two (43 pieces). In 1945, Bartók revised the set, removing six pieces which used tunes which had been inaccurately transcribed or found not to be original folk tunes, and substantially changing the harmonisation of a number of others; the cycle, now of 79 pieces, was reissued in two volumes (of 40 and 39 pieces).

The pieces were written as student works, and progress slightly in difficulty through each half of the cycle. However, in modern times, some concert pianists (notably Zoltán Kocsis) have begun including some of them on their recital programs, citing their musical value even apart from their pedagogical origins.
