A musical cryptogram is a cryptogrammatic sequence of musical symbols which can be taken to refer to an extra-musical text by some 'logical' relationship, usually between note names and letters. The most common and best known examples result from composers using musically translated versions of their own or their friends' names (or initials) as themes or motifs in their compositions. These are not really rigorous cipher algorithms in the formal sense, but more like musical monograms. The methods used historically by composers were either too incomplete (i.e., did not include all of the letters of the alphabet) or too simplistic to meaningfully encrypt long text messages. There is a separate history of music ciphers utilizing music notation to encode messages for reasons of espionage or personal security that involved encryption and/or steganography.
Because of the multitudinous ways in which notes and letters can be related, detecting hidden ciphers in music and proving accurate decipherment can be difficult.
From the initial assignment by Western music theorists of letter names to notes in the 9th century [1] it became possible to reverse the procedure and assign notes to the letters of names. However, this does not seem to have become a widely recognized technique until the Romantic period. From the mid-19th century it has become quite common. Sporadic earlier encipherments used solmization syllables.
It is believed that this method was first used by Josquin des Prez in his Missa Hercules Dux Ferrarie. It was named Soggetto cavato by the later theorist Zarlino. Under this scheme the vowel sounds in the text are matched to the vowel sounds of the solmization syllables of Guido of Arezzo (where 'ut' is the root, which we now call 'do'). Thus the Latin name of the dedicatee 'Hercules Dux Ferrarie' (Ercole d'Este, Duke of Ferrara) becomes re-ut-re-ut-re-fa-mi-re, which translates as D-C-D-C-D-F-E-D in modern notation with C as 'ut'. This is used as the cantus firmus of the mass setting. Josquin's method was imitated by several of his contemporaries and successors, including Adrian Willaert and Costanzo Festa.
Since the note names only cover letters A to G (reflecting the octave repetition of these names), the problem arises as to how to cipher the rest of the alphabet. Historically there have been two main solutions, which may be labelled for convenience the 'German' and the 'French' methods. [2]
Because the development of note names took place within the framework of modes, in the German-speaking world B-flat was named 'B' and B-natural was named 'H'. The most common musical cryptogram is the B-A-C-H motif, which was used by Johann Sebastian Bach himself, by his contemporaries and by many later composers. Other note names were derived by sound, for example E-flat, 'Es' in German, could represent 'S' and A-flat the digraph 'As'.
Composers less fortunate than Bach usually seem to have chosen to ignore non-musical letters in generating their motifs. For example, Robert Schumann, an inveterate user of cryptograms, has just S-C-H-A (E-flat, C, B-natural, A) to represent himself in Carnaval . Sometimes phonetic substitution could be used, Schumann representing Bezeth by B-E-S-E-D-H. Johannes Brahms used B-A-H-S (B-flat, A, B-natural, E-flat) for his surname in the A-flat minor organ fugue, and the mixed language Gis-E-La (G-sharp, E, A) for Gisela von Arnim, among many examples. [3]
The 'French' method of generating cryptograms arose late in the 19th century and was more akin to normal encipherment. The most popular version involved writing out the letters H-N, O-U and V-Z in lines under the original diatonic notes A-G, as follows:
A | B | C | D | E | F | G |
---|---|---|---|---|---|---|
H | I | J | K | L | M | N |
O | P | Q | R | S | T | U |
V | W | X | Y | Z |
so that A, H, O, and V are enciphered by note 'A', B, I, P and W by 'B' (flat or natural) and so on. [4] This scheme was used by Jules Écorcheville, editor of the journal S.I.M., to solicit centenary commemorations of Joseph Haydn in 1909, except that he diverted the 'H' to B-natural, presumably to avoid too many repeated notes. [3] Writing to Gabriel Fauré about the invitation, Camille Saint-Saëns said he was writing to Écorcheville asking him to prove that Y and N could signify D and G as "it would be annoying to get mixed up in a farcical business which would make us a laughing stock in the German musical world." [5] The many-to-one mapping of this method makes it more difficult to extract possible motifs from the musical score than the one-to-one correspondence (apart from 'As') of the German system.
A French tradition of celebratory uses developed from the Haydn centenary, with tributes to Gabriel Fauré by Maurice Ravel, Florent Schmitt, Charles Koechlin and others in 1922 (added to later by Arnold Bax, 1949 [6] ) and to Albert Roussel by Francis Poulenc, Arthur Honegger, Darius Milhaud and others (using various ciphering schemes) in 1929. Honegger's system involved placing the letters after 'H' under sharpened and flattened notes, [3] an example of how chromatic cryptograms could be more easily accommodated in 20th-century music. [7]
Olivier Messiaen developed his own full cipher, involving pitches and note lengths, for his organ work Méditations sur le mystère de la Sainte Trinité (1969). [8] [9]
Dmitri Shostakovich used the German scheme for his personal motto D-Es-C-H (D, E-flat, C, B-natural), representing D.SCH, which appears in many of his works. Elliott Carter featured both a cryptogram for the last name "Boulez" in his piece Réflexions (2004) and a sonic symbol of the first name "Pierre". [10]
Cryptograms were less common in England, but Edward Elgar, who was also interested in general cryptography and puzzles, wrote an early Allegretto for his pupils the Gedge sisters using G-E-D-G-E [11] and part of the 'enigma' in the Enigma Variations involves cryptograms.
In 1947 Friedrich Smend suggested that Bach enciphered significant numbers through methods including repetitions of a motif, word, or phrase; the notes played on the continuo; the use of sequence; and the notes played by the accompaniment. However, Ruth Tatlow has presented evidence questioning the plausibility of Smend's claims. [12]
During the first quarter of the 20th century, American author and occultist Paul Foster Case established an esoteric musical cryptogram for the purposes of ceremonial magick. The system was a derivative of a cipher used by an affiliated magical order called the Hermetic Order of the Golden Dawn. [13] Each note of the 12 tone system was assigned a set of correspondences including colors, planets, zodiacal signs, and Hebrew letters. The holy names of biblical characters were translated letter by letter into a linear sequence of musical notes, so that each letter could be sung by the congregation in unison.
Ezra Sandzer-Bell has written and published two books on this subject, [14] describing how Paul Foster Case's system of musical cryptography could be applied to songwriting. Any word can be translated phonetically into Hebrew and converted using Case's cryptogram to generate a series of notes. Sandzer-Bell's project involves the conversion of the common and Latin names of plants, trees, and mushrooms into melodies. Each song was composed by consuming the plant in tea or tincture form, then using the physical effects of the plant to determine what kind of rhythm, harmony, instruments, and dynamics to use. A lengthy demonstration and proof concept is publicly available on the author's website. [15]
Solfa Cipher, invented in 2013, uses a combination of scale degrees and rhythms to represent letters of the alphabet with the goal generating encrypted texts which sound like relatively normal singable melodies. [16] As such, it has been used by musicians to create longer pieces with hidden messages. It has also been featured as a plot device in mysteries such as Gary McAvoy's Vivaldi Cipher. [17] and purportedly the video game Fortnite. [18]
The following list includes only motifs which are known to have been used in published works.
In Western musical notation, a key signature is a set of sharp, flat, or rarely, natural symbols placed on the staff at the beginning of a section of music. The initial key signature in a piece is placed immediately after the clef at the beginning of the first line. If the piece contains a section in a different key, the new key signature is placed at the beginning of that section.
The major scale is one of the most commonly used musical scales, especially in Western music. It is one of the diatonic scales. Like many musical scales, it is made up of seven notes: the eighth duplicates the first at double its frequency so that it is called a higher octave of the same note.
In music, notes are distinct and isolatable sounds that act as the most basic building blocks for nearly all of music. This discretization facilitates performance, comprehension, and analysis. Notes may be visually communicated by writing them in musical notation.
In musical notation, an accidental is a symbol that indicates an alteration of a given pitch. The most common accidentals are the flat and the sharp, which represent alterations of a semitone, and the natural, which cancels a sharp or flat. Accidentals alter the pitch of individual scale tones in a given key signature; the sharps or flats in the key signature itself are not considered accidentals.
In music, sharp – eqv. dièse or diesis – means higher in pitch. The sharp symbol, ♯, indicates that the note to which the symbol is applied is played one semitone higher. The opposite of sharp is flat, indicating a lowering of pitch. The ♯ symbol derives from a square form of the letter b.
In music, flat means lower in pitch. It may either be used generically, meaning any lowering of pitch, or refer to a particular size: lowering pitch by a chromatic semitone. A flat is the opposite of a sharp which raises pitch by the same amount that a flat lowers it.
In music, the BACH motif is the motif, a succession of notes important or characteristic to a piece, B flat, A, C, B natural. In German musical nomenclature, in which the note B natural is named H and the B flat named B, it forms Johann Sebastian Bach's family name. One of the most frequently occurring examples of a musical cryptogram, the motif has been used by countless composers, especially after the Bach Revival in the first half of the 19th century.
The String Quartet, Op. 28, by Anton Webern is written for the standard string quartet group of two violins, viola and cello. It was the last piece of chamber music that Webern wrote.
B, also known as Si, Ti, or, in some European countries, H, is the seventh note and the twelfth semitone of the fixed-Do solfège. Its enharmonic equivalents are C♭ (C-flat) and A.
Carnaval, Op. 9, is a work by Robert Schumann for piano solo, written in 1834–1835 and subtitled Scènes mignonnes sur quatre notes. It consists of 21 short pieces representing masked revelers at Carnival, a festival before Lent. Schumann gives musical expression to himself, his friends and colleagues, and characters from improvised Italian comedy. He dedicated the work to the violinist Karol Lipiński.
When a musical key or key signature is referred to in a language other than English, that language may use the usual notation used in English : languages which use the English system include Irish, Welsh, Hindi, Japanese, Korean, Chinese, Thai, Indonesian, Filipino, Swahili, Esperanto.
DSCH is a musical motif used by the composer Dmitri Shostakovich to represent himself. It is a musical cryptogram in the manner of the BACH motif, consisting of the notes D, E-flat, C, B natural, or in German musical notation D, Es, C, H, thus standing for the composer's initials in German transliteration: D. Sch..
The Variations on the name "Abegg" in F major is a piece for piano by Robert Schumann, composed between 1829 and 1830, while as a student in Heidelberg, and published as his Opus 1. The name is believed to refer to Schumann's fictitious friend, Meta Abegg, whose surname Schumann used through a musical cryptogram as the motivic basis for the piece. The name Meta is considered to be an anagram of the word "tema" (Latin). Another suggestion is Pauline von Abegg. Apparently, when he was twenty years old, Schumann met her and dedicated this work to her, as witnessed in Clara Schumann's edition of her husband's piano works.
F is a musical note, the fourth above C or fifth below C. It is the fourth note and the sixth semitone of the solfège. It is also known as fa in fixed-do solfège. It is enharmonic equivalent with E♯ (E-sharp) and G, amongst others.
In modern Western music notation, a natural (♮) is a musical symbol that cancels a previous sharp or flat on a note in the written music. The natural indicates that the note is at its unaltered pitch.
B♭ (B-flat), or, in some European countries, B, is the eleventh step of the Western chromatic scale. It lies a diatonic semitone above A and a chromatic semitone below B, thus being enharmonic to A♯, even though in some musical tunings, B♭ will have a different sounding pitch than A♯. B-flat is also enharmonic to C.
E♭ (E-flat) or mi bémol is the fourth semitone of the solfège.
The Piano Quartet No. 3 in C minor, Op. 60, completed by Johannes Brahms in 1875, is scored for piano, violin, viola and cello. It is sometimes called the Werther Quartet after Goethe's The Sorrows of Young Werther. The premiere took place in Vienna on November 18, 1875, to an anxious public. Richard Wagner and his wife Cosima were in attendance.
Clavier-Übung II is a collection of harpsichord works by Johann Sebastian Bach. It was published in 1735. Written for performance on a two-manual harpsichord, it contrasts the Italian style of that time with the French style. While the Italian style is represented by the Italian Concerto, BWV 971, the French style is represented by the suite Overture in the French style, BWV 831.
The C. F. E. BACH motif is a musical motif, consisting of the notes C, F, E, B♭, A, C, B♮. The motif is a musical cryptogram, which represents the name of Carl Philipp Emanuel Bach with the initials of his name – Carl Philipp (Filippo) Emanuel Bach. The motif is based on the German note names, in which the note B♮ is named H and B♭ is named B, just as in the BACH motif. However, the initials of the composer’s name appear in a mixture of German and Italian, with Philipp rendered as Filippo.
the 'Eschbeg set,' Schoenberg's musical signature." and "the 'A. Schbeg' (or 'Aschbeg') set.
