Crystallinity
Crystallinity refers to the degree of structural order in a solid. In a crystal, the atoms or molecules are arranged in a regular, periodic manner. The degree of crystallinity has a big influence on hardness, density, transparency and diffusion. In a gas, the relative positions of the atoms or molecules are completely random. Amorphous materials, such as liquids and glasses, represent an intermediate case, having order over short distances (a few atomic or molecular spacings) but not over longer distances.
Many materials, such as glass-ceramics and some polymers, can be prepared in such a way as to produce a mixture of crystalline and amorphous regions. In such cases, crystallinity is usually specified as a percentage of the volume of the material that is crystalline. Even within materials that are completely crystalline, however, the degree of structural perfection can vary. For instance, most metallic alloys are crystalline, but they usually comprise many independent crystalline regions (grains or crystallites) in various orientations separated by grain boundaries; furthermore, they contain other crystal defects (notably dislocations) that reduce the degree of structural perfection. The most highly perfect crystals are silicon boules produced for semiconductor electronics; these are large single crystals (so they have no grain boundaries), are nearly free of dislocations, and have precisely controlled concentrations of defect atoms.
Crystalline (song)
"Crystalline" is a song by Icelandic artist Björk, released as the lead single from her eighth album Biophilia. The song was released as a single on June 28, 2011 accompanied by an iPad app developed exclusively for the song. It was afterward released as part of The Crystalline Series alongside the second single from the album, "Cosmogony".
Development
In March 2011 it was announced that Björk would play at the Manchester International Festival with a new concept of concert. Several songs from the album debuted during a series of performances at the festival between June 27 and July 16, 2011. Björk called the performances a "meditation on the relationship between music, nature and technology". "Special" instruments were designed and constructed specifically for these concerts.
The release of the song was preceded by three teasers: on the first one, entitled "Road to Crystalline" we can see Björk driving her Hummer through a road in Iceland while playing an excerpt of a demo version of the song; on the second one, we could see one of the new instruments developed for the Manchester performances, that also plays on the track: the 'Gameleste', a celesta which was modified by Icelandic Organ builder, Björgvin Tómasson and British Cymbalsmith and Gong maker, Matt Nolan so that it sounds like Gamelan and could be played remotely by MIDI or even an iPad; and on the third teaser, recording sessions of the remix featuring Omar Souleyman were shown. The song leaked onto the internet on June 25, 2011. On June 28, 2011, UK producers 16bit confirmed via Facebook that they produced the song.
