ASK! about Performing Arts

In today’s context, music publishing is no longer limited to just publishing of music in print. The business of music publishing has now expanded and branched out to other aspects such as the protection of copyrights of the original music by the artiste(s), record companies, online music business, compiling the sheet music, transcribers (perfect for those who have a good ear for music), and also record royalties.

Within the print business of the music publishing industry, there are 3 main areas:
1. standard music publishing in classical and serious contemporary music;
2. educational music publishing in music instructional books; &
3. popular music publishing.

Some examples of music publishers are Schirmer (classical and new music), Hal Leonard ( a compendium of music styles, including instructional), and Music Sales (songbooks and educational titles).
You can refer to their websites as cited below:
http://www.schirmer.com
http://halleonard.com
http://www. musicsales.com

Owing to the rampant spread of music being easily downloadable online and the threat of piracy, music publishers now strive to protect the copyright of the original music they own to prevent infringement, and the detrimental cause-and-effects consequences caused by music being freely distributed, be they in print, online, or sound recordings.

In Singapore, the MPS (Music Publishers) is formed to do just that. For more information, please go to http://www.mps.org.sg/

“On Earth, the sky is bright during the day because air molecules reflect and scatter sunlight. Stars cannot be seen because the daytime sky is brighter than the stars. The Moon is seen during the day since it is brighter than the daytime sky. On the Moon, however, there is no atmosphere, so the sky is dark and the stars are out, even during the day. Even near the blazing Sun, space stays black because space itself is very empty.”

It is not true that only girls keep their hair long. Some men also prefer to grow their hair long while others do so for religious purposes.

You can find an article on men having long hair at Hairfinder: International Hair Directory.

“Keeping their hair uncut is one of the religious obligations of Sikh males. In the Sikh religion, hair is considered a gift from God. Covering the hair with a turban is a tradition that dates from the 16th century, when Guru Nanak founded the Sikh religion.”

“The history of the barber pole is intertwined with the history of barbers and their bloodletting practices. Patients would grasp a rod or staff tightly so that their veins would show, and the barbers would cut open their arms and bleed them until they fainted (nasty but true)…

Most fish spend part of every day asleep. Being asleep can mean different things to different fish. Some fish (like herring and tuna) are motionless in the water during the night. Other fish, like rockfish and grouper, don’t appear to sleep at all. They rest against rocks, bracing themselves with their fins. Because of the nature of their eye (lacking an eyelid), they do not ‘close’ their eyes when they are sleeping.

ASK! about Recreation

According to these related website sources: (last accessed: 26 May07)
“In tennis, a zero is called love, which is a corruption of the French word l’oeuf (an egg, which has a round shape like a zero).”
(Extracted from Source: Spanish Lesson 21
http://www.wvup.edu/Academics/humanities/
Oldaker/spanish_lesson_21.htm)

“Court tennis, an ancestor of most of today’s racket games, originated in 14th century France. Pronounced correctly “l’oeuf”—meaning “egg”—sounds similar to “love.” And the egg, which unquestionably looks like a zero, could have been used to describe a zero written on a scoreboard.”
(Extracted from Source: “The Meaning of Love.” Ask the Editors. Infoplease.
© 2000–2007 Pearson Education, publishing as Infoplease.
25 May. 2007 )

0, or nothing, is called ‘love’. It is believed to come from the pronunciation of the French word ‘l’ oeuf’, which sounds like ‘love. The use of ‘l’ouef’, meaning ‘egg’, to denote nothing, is derived from the shape of an egg.
