Key coloration is the difference between the intervals of different keys in a single non-equal tempered tuning, and the overall sound and "feel" of the key created by the tuning of its intervals. Historical irregular musical temperaments usually have the narrowest fifths between the diatonic notes ("naturals") producing purer thirds , and wider ...
A major interval is one semitone larger than a minor interval. The words perfect, diminished and augmented are also used to describe the quality of an interval.Only the intervals of a second, third, sixth, and seventh (and the compound intervals based on them) may be major or minor (or, rarely, diminished or augmented).

Key signatures can theoretically be extended through double flats or double sharps and beyond, but this is extremely rare. For example, the key of G ♯ major would have eight sharps, requiring six single sharps and an F double-sharp (F). The key of A ♭ major, with four flats, is enharmonically equivalent and would generally be used instead.
A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, ...
Example of a Key Derivation Function chain as used in the Signal Protocol.The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a ...
An additional advantage is a stuck key can be removed from a shaft with a hammer blow, the circular profile will push the key out of the slot, as opposed to a standard key which will need to be pushed axially, or pulled out of its slot. Common applications include machine tools, automotive applications, snowblowers and marine propellers.
In biology, an identification key, taxonomic key, or frequently just key, is a printed or computer-aided device that aids in the identification of biological organisms. Historically, the most common type of identification key is the dichotomous key , a type of single-access key which offers a fixed sequence of identification steps, each with ...
