Horology is the study of the measurement of time. Clocks, clockwork, hourglasses, timers, time recorders, marine chronometers, atomic clocks are all examples of instruments used to measure time. In current usage, horology refers to the study of mechanical time-keeping devices, while chronometry more broadly includes electronic devices that have supplanted mechanical clocks for the best accuracy and precision in time-keeping. People interested in horology are called horologists; that term is used both by people who deal professionally with timekeeping apparatus, as well as aficionados and scholars of horology. Horology and horologists have numerous organizations, both professional associations and more scholarly societies; the largest horological membership organisation globally is the NAWCC, the National Association of Watch and Clock Collectors, USA based, but has local chapters elsewhere. There are several specialized libraries devoted to the subject. One example is the Royal Greenwich Observatory, the source of the Prime Meridian, the home of the first marine timekeepers accurate enough to determine longitude.

Other horological museums in the London area include the Clockmakers' Museum, which re-opened at the Science Museum in October 2015, the horological collections at the British Museum, the Science Museum, the Wallace Collection. In Upton, UK, at the headquarters of the British horological Institute, Upton hall, is the Museum of time keeping. One of the more comprehensive museums dedicated to horology is the Musée international d'horlogerie in La Chaux-de-Fonds; the Musée d'Horlogerie du Locle is smaller but located nearby. One of the better horological museums in Germany is the Deutsches Uhrenmuseum in Furtwangen im Schwarzwald, in the Black Forest; the two leading specialised horological museums in North America are the National Watch and Clock Museum in Columbia and the American Clock and Watch Museum in Bristol, Connecticut. The eastern French city of Besançon has the Musée du Temps in the historic Palais Grenvelle. An example of a museum devoted to one particular type of clock is the Cuckooland Museum in the UK, which hosts the world's largest collection of antique cuckoo clocks.

One of the most comprehensive horological libraries open to the public is the National Watch and Clock Library in Columbia, Pennsylvania. Other good horological libraries providing public access are at the Musée international d'horlogerie in Switzerland, at the Deutsches Uhrenmuseum in Germany, at the Guildhall Library in London. Another museum dedicated to clocks is the Willard Clock Museum in Grafton, Massachusetts.

Guangdong music (genre)

Guangdong music known as Cantonese music is a style of traditional Chinese instrumental music from Guangzhou and surrounding areas in Pearl River Delta of Guangdong Province on the southern coast of China. The name of the music is not an accurate description because Guangdong music is not the only music of the whole Guangdong area. Cantonese classical music were much livelier in pace and happier than those of other China provinces, typical and the essence of the Cantonese's character. In Guangdong, there are numerous traditional genres of music such as Hakka music; the name of the music originated in the 1920 and 1930s when the music was popular in Shanghai ballrooms in the form of "Spiritual Music". As the performers were entirely from Guangdong, Shanghai people generalized the form of music as Guangdong music. Musically, compositions are based on tunes derived from Cantonese opera, together with new compositions from the 1920s onwards; some pieces have influences from jazz and Western music, using syncopation and triple time, incorporating instruments such as the saxophone, guitar, drum set, or xylophone.

The gaohu is the most common lead instrument used in performing Cantonese music. It was invented by Lü Wencheng in the 1920s. Prior to this, the erxian was the most common lead bowed string instrument in the Cantonese ensemble. Ensembles led by the erxian and featuring the tiqin are called yinggong ensembles, while those led by the gaohu are called ruangong because the erxian and tiqin have thick bamboo bows, while the gaohu has a thinner, flexible bow. Guangdong music evolved into a string ensemble format by the 1960s, led by the gaohu with ruan, yangqin, yehu and various woodwind and percussion instruments.
