Q:Information:  - Electronic music is music that employs electronic musical instruments and electronic music technology in its production, an electronic musician being a musician who composes and/or performs such music. In general, a distinction can be made between sound produced using electromechanical means and that produced using electronic technology. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar. Purely electronic sound production can be achieved using devices such as the theremin, sound synthesizer, and computer.  - Electronica is an umbrella term that encompasses a broad group of electronic - based styles such as techno , house , ambient , drum and bass , jungle , and industrial dance , among others . It has been used to describe the rise of electronic music styles intended not just for dancing but also concentrated listening .  - Detroit is the most populous city in the U.S. state of Michigan, the fourth-largest city in the Midwest and the largest city on the United StatesCanada border. It is the seat of Wayne County, the most populous county in the state.  - A synthesizer (often abbreviated as synth, also spelled synthesiser) is an electronic musical instrument that generates electric signals that are converted to sound through instrument amplifiers and loudspeakers or headphones. Synthesizers may either imitate instruments like piano, Hammond organ, flute, vocals; natural sounds like ocean waves, etc.; or generate new electronic timbres. They are often played with a musical keyboard, but they can be controlled via a variety of other input devices, including music sequencers, instrument controllers, fingerboards, guitar synthesizers, wind controllers, and electronic drums. Synthesizers without built-in controllers are often called "sound modules", and are controlled via MIDI or CV/Gate using a controller device, often a MIDI keyboard or other controller.  - Detroit techno is a type of techno music that generally includes the first techno productions by Detroit-based artists during the 1980s and early 1990s. Detroit has been cited as the birthplace of techno. Prominent Detroit techno artists include Juan Atkins, Eddie Fowlkes, Derrick May, Jeff Mills, Kevin Saunderson, Blake Baxter, Santonio Echols and Mike Banks.  - Jungle (sometimes oldschool jungle), is a genre of electronic music that developed in England in the early 1990s as part of rave music scenes. The style is characterized by fast tempos (150 to 200 bpm), relatively slow and lyrical reggae-derived basslines, breakbeats, and other heavily syncopated percussive loops, samples and synthesized effects make up the easily recognizable form of jungle. Long pitch-shifted snare rolls are common in oldschool jungle. The terms "jungle" and "drum and bass" are often used interchangeably, although whether the two genres are actually distinct is an ongoing topic of debate. For those individuals who consider the two genres as separate entities, drum and bass is usually considered to have departed from jungle in the mid to late 1990s.  - Genre (or ; from French "genre" , "kind" or "sort", from Latin "genus" (stem "gener-"), Greek , "gés")   - England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight.  - Cryptanalysis (from the Greek "kryptós", "hidden", and "analýein", "to loosen" or "to untie") is the study of analyzing information systems in order to study the hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown.  - Michigan is a state in the Great Lakes and Midwestern regions of the United States. The name Michigan is the French form of the Ojibwa word "mishigamaa", meaning "large water" or "large lake". Michigan is the tenth most populous of the 50 United States, with the 11th most extensive total area (the largest state by total area east of the Mississippi River). Its capital is Lansing, and its largest city is Detroit.  - Techno is a form of electronic dance music that emerged in Detroit, Michigan, in the United States during the mid-to-late 1980s. The first recorded use of the word "techno" in reference to a specific genre of music was in 1988. Many styles of techno now exist, but Detroit techno is seen as the foundation upon which a number of subgenres have been built.  - Electronic dance music (also known as EDM, dance music, club music, or simply dance) is a broad range of percussive electronic music genres made largely for nightclubs, raves, and festivals. EDM is generally produced for playback by disc jockeys (DJs) who create seamless selections of tracks, called a mix, by segueing from one recording to another. EDM producers also perform their music live in a concert or festival setting in what is sometimes called a live PA. In the United Kingdom and in continental Europe, EDM is more commonly called 'dance music' or simply 'dance'.   - Breakbeat as a term refers to one of two distinct things. Originally it would have referred only to "A breakbeat" (1), a section of a song in which, typically, all or at least most of the instruments stop for a period, usually around one bar, except for the drums, which would continue the melody even if altered. Since the rise of electronic music it can now also refer to the electronic music genre "Breakbeat" (2), characterized as a genre of groove-oriented music which utilizes a lo-fi sampled breakbeat (or combination of breakbeats) for the main drum beat, and usually incorporates other lo-fi sampled "hits" as well.  - Cryptography or cryptology (from Greek "kryptós", "hidden, secret"; and "graphein", "writing", or "-logia", "study", respectively) is the practice and study of techniques for secure communication in the presence of third parties called adversaries. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce.  - An umbrella term is a word or phrase that covers a broad interval or set of functions or items that all fall under a single common category. For example, "cryptology" is an umbrella term that encompasses cryptography and cryptanalysis, among other fields. Similarly, an umbrella organization is a central and coordinating body representing a number of smaller, separate bodies.  - An umbrella organization is an association of (often related, industry-specific) institutions, who work together formally to coordinate activities or pool resources. In business, political, or other environments, one group, the umbrella organization, provides resources and often an identity to the smaller organizations. Sometimes in this kind of arrangement, the umbrella organization is to some degree responsible for the groups under its care. Compare to franchises and subsidiaries.  - Drum and bass (also written as "drum 'n' bass", "drum & bass" and commonly abbreviated as "D&B", "DnB" or "D'n'B") is a genre and branch of electronic music which emerged from rave and oldschool jungle scenes in England during the early 1990s. The style is often characterized by fast breakbeats (typically between 150180 beats per minute) with heavy bass and sub-bass lines, sampled sources, and synthesizers.  - Sub-bass sounds are the deep, low- register pitched pitches approximately below 60 Hz and extending downward to include the lowest frequency humans can hear, typically 20 Hz. In this range, human hearing is not very sensitive, so sounds in this range tend to be felt more than heard. Sound reinforcement systems and PA systems often use one or more subwoofer loudspeaker cabinets that are dedicated solely to amplifying sounds in the sub-bass range. Sounds below sub-bass are called infrasound.    After reading the paragraphs above, we are interested in knowing the entity with which 'electronica' exhibits the relationship of 'instance of'.
