Music Cipher
In cryptography, a music cipher is an algorithm for the encryption of a plaintext into musical symbols or sounds. Music-based ciphers are related to, but not the same as musical cryptograms. The latter were systems used by composers to create musical Subject (music), themes or motif (music), motifs to represent names based on similarities between letters of the alphabet and musical note names, such as the BACH motif, whereas music ciphers were systems typically used by cryptographers to hide or code, encode messages for reasons of secrecy or espionage. Types There are a variety of different types of music ciphers as distinguished by both the method of encryption and the musical symbols used. Regarding the former, most are simple substitution ciphers with a one-to-one correspondence between individual letters of the alphabet and a specific musical note. There are also historical music ciphers that utilize homophonic substitution (one-to-many), polyalphabetic substitution, polyphonic ...

Clef
A clef (from French: 'key') is a musical symbol used to indicate which notes are represented by the lines and spaces on a musical staff. Placing a clef on a staff assigns a particular pitch to one of the five lines or four spaces, which defines the pitches on the remaining lines and spaces. The three clef symbols used in modern music notation are the G-clef, F-clef, and C-clef. Placing these clefs on a line fixes a reference note to that line—an F-clef fixes the F below middle C, a C-clef fixes middle C, and a G-clef fixes the G above middle C. In modern music notation, the G-clef is most frequently seen as treble clef (placing G4 on the second line of the staff), and the F-clef as bass clef (placing F3 on the fourth line). The C-clef is mostly encountered as alto clef (placing middle C on the third line) or tenor clef (middle C on the fourth line). A clef may be placed on a space instead of a line, but this is rare. The use of different clefs makes it possible t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Half Note
In music, a half note (American) or minim (British) is a Musical note, note played for half the duration of a whole note (or semibreve) and twice the duration of a quarter note (or crotchet). It was given its Latin name (''minima'', meaning "least or smallest") because it was the shortest of the five note values used in mensural notation, early medieval music notation. Half notes are notated with a hollow oval notehead like a whole note and straight note stem with no flag (music), flags like a quarter note (see Figure 1). The half rest (or minim rest) denotes a silence of the same duration. Half rest (music), rests are drawn as filled-in rectangles sitting on top of the middle line of the musical staff, although in polyphonic music the rest may need to be moved to a different line or even a ledger line. As with all notes with stems, half notes are drawn with upward stems on the right when they are below the middle line of the staff and downward stems on the left when they are on ...

Whole Note
A whole note (American) or semibreve (British) in musical notation is a single note equivalent to or lasting as long as two half notes or four quarter notes. Description The whole note or semibreve has a note head in the shape of a hollow oval—like a half note (or ''minim'')—but with no note stem (see Figure 1). Since it is equal to four quarter notes, it occupies the entire length of a bar_(music), measure in time signature, time. Other notes are multiples or fractions of the whole note. For example, a double whole note (or ''breve'') lasts twice the duration of the whole note, a half note lasts one half the duration, and a quarter note (or ''crotchet'') lasts one quarter the duration. A related symbol is the whole rest (music), rest (or semibreve rest), which signifies a rest for the duration of a whole note. Whole rests are drawn as filled-in rectangles generally hanging under the second line from the top of a musical staff, though they may occasionally be put under ...

De Furtivis Literarum Notis
''De Furtivis Literarum Notis'' (''On the Secret Symbols of Letters'') is a 1563 book on cryptography written by Giambattista della Porta. The book includes three sets of cypher discs for coding and decoding messages, a substitution cipher improving on the work of Al-Qalqashandi Shihāb al-Dīn Abū 'l-Abbās Aḥmad ibn ‘Alī ibn Aḥmad ‘Abd Allāh al-Fazārī al-Shāfiʿī better known by the epithet al-Qalqashandī (; 1355 or 1356 – 1418), was a medieval Arab Egyptian encyclopedist, polymath and mathemati ..., and one of the earliest known music substitution ciphers.

Philip Music Cipher
Philip, also Phillip, is a male name derived from the Greek (''Philippos'', lit. "horse-loving" or "fond of horses"), from a compound of (''philos'', "dear", "loved", "loving") and (''hippos'', "horse"). Prominent Philips who popularized the name include kings of Macedonia and one of the apostles of early Christianity. ''Philip'' has many alternative spellings. One derivation often used as a surname is Phillips. The original Greek spelling includes two Ps as seen in Philippides and Philippos, which is possible due to the Greek endings following the two Ps. To end a word with such a double consonant—in Greek or in English—would, however, be incorrect. It has many diminutive (or even hypocoristic) forms including Phil, Philly, Phillie, Lip, and Pip. There are also feminine forms such as Philippine and Philippa. Philip in other languages * Afrikaans: Filip * Albanian: Filip * Amharic: ፊሊጶስ (Filip'os) * Arabic: فيلبس (Fīlibus), فيليبوس (Fīlībū ...

Stem (music)
In musical notation, stems are the "thin, vertical lines that are directly connected to the otehead." Stems may point up or down. Different-pointing stems indicate the voice for polyphonic music written on the same staff. Within one voice, the stems usually point down for notes on the middle line or higher, and up for those below. If the stem points up from a notehead, the stem originates from the right-hand side of the note, but if it points down, it originates from the left. If there are multiple notes beamed together, the stem's direction is defined by the average of the lowest and highest notes in the beam. There is an exception to this rule: if a chord contains a second, the stem runs between the two notes with the higher being placed on the right of the stem and the lower on the left. If the chord contains an odd numbered cluster of notes a second apart (such as C, D, E), the outer two will be on the correct side of the stem, while the middle note will be on the wrong s ...

Bacon's Cipher
Bacon's cipher or the Baconian cipher is a method of steganographic message encoding devised by Francis Bacon in 1605. In steganography, a message is concealed in the presentation of text, rather than its content. Baconian ciphers are categorized as both a substitution cipher (in plain code) and a concealment cipher (using the two typefaces). Cipher details To encode a message, each letter of the plaintext is replaced by a group of five of the letters 'A' or 'B'. This replacement is a 5-bit binary encoding and is done according to the alphabet of the Baconian cipher (from the Latin Alphabet), shown below: A second version of Bacon's cipher uses a unique code for each letter. In other words, ''I'', ''J'', ''U'' and ''V'' each have their own pattern in this variant: The writer must make use of two different typefaces for this cipher. After preparing a false message with the same number of letters as all of the ''As'' and ''Bs'' in the real, secret message, two typefaces ar ...
