Megatokyo(メガトーキョー) (also stylized as MegaTokyo) is an English-language webcomic created by Fred Gallagher and Rodney Caston. Megatokyo debuted on August 14, 2000, and has been written and illustrated solely by Gallagher since July 17, 2002. Gallagher's style of writing and illustration is heavily influenced by Japanese manga. Megatokyo is freely available on its official website. The stated schedule for updates is Tuesday and Friday, but they typically are posted just once or twice a month on non-specific days (in the beginning a three-per-week schedule of Monday, Wednesday, and Friday was the goal). Recently, this schedule has slipped further, due to the health issues of Sarah Gallagher (Seraphim), Fred's wife. Megatokyo was also published in book-format by CMX, although the first three volumes were published by Dark Horse. For February 2005, sales of the comic's third printed volume were ranked third on BookScan's list of graphic novels sold in bookstores, then the best showing for an original English-language manga.
A piece of music's tempo is typically written at the start of the score, and in modern Western music is usually indicated in beats per minute (BPM). This means that a particular note value (for example, a quarter note, or crotchet) is specified as the beat, and that the amount of time between successive beats is a specified fraction of a minute. The greater the number of beats per minute, the smaller the amount of time between successive beats, and thus faster a piece must be played. For example, a tempo of 60 beats per minute signifies one beat per second, while a tempo of 120 beats per minute is twice as rapid, signifying one beat every 0.5 seconds. Mathematical tempo markings of this kind became increasingly popular during the first half of the 19th century, after the metronome had been invented by Johann Nepomuk Maelzel, although early metronomes were somewhat inconsistent. Beethoven was one of the first composers to use the metronome; in the 1810s he published metronomic indications for the eight symphonies he had composed up to that time. for example a minum has a 2 seconds
