Eye Music

Eye music (often referred to in English by its exact German translation ''Augenmusik'') describes graphical features of scores which when performed are unnoticeable by the listener.

Difficulties in defining eye music

By simple definition eye music is when the graphic notation of music is altered in some meaningful way visible to the performers. Often the changed "meaning" of the altered notation is enhanced by the music having compositional elements of melody and form such as word painting and canon. Moreover, the concept is demonstrated by sometimes differing perceptions of composer, performer, and listener.Dart, Thurston. "Eye music." New Grove Dictionary of Music and Musicians, Stanley Sadie, ed. London:Macmillan, 1980.

Eye music and puzzle-solving

The difficulty in definition is also apparent with border-line cryptographic contrapuntal works such as puzzle canons, which appear in the score entirely as a bare line of notes with clefs, rests, time signatures, key signatures or brief cryptic clues in Latin to reveal multiple lines of music in canons of diminution, augmentation, etc. (Closer to true cryptographic works would be those with soggetto cavato, where letters are embedded in the work using their solfège names.) As an example, a puzzle canon might be notated as one line of music with two key signatures and clefs, where the worked-out result will be a two-voice canon with one voice the retrograde (reverse) of the other. In itself the score with the clues alone is not eye music. But represent the same work "graphically spelled out," however, say with a drawing of the clued score facing a mirror, and the score/drawing becomes eye music.

The ''type'' of puzzle canon is also a factor. A four-voiced circular canon, when notated as a puzzle canon, may remain an un-worked-out single line of notes, and be inadmissible as eye music. When that single line of notes is inscribed in a graphical shape it becomes eye music, even if the contrapuntal puzzle remains unsolved.

An even finer use of graphical conceit is when the canon does not have any musical way to end, and are in a sense "infinite"—classically referred to as ''canon perpetuus,'' more commonly as "circular canons," and even more commonly as " rounds." When an infinite (circular) canon is inscribed in a circle, and the ''circle itself'' is a clue that means "play me as a round," a different type of eye music entails.

Eye music for the performer

Another class of eye music is when the score is purposely made difficult for the performer. For example, in Benedetto Marcello's cantata ''Stravaganze d’amore,'' the continuo part is written entirely in enharmonic chords, that is, "puns" of chord indications spelled with no regard to the key of the rest of the ensemble, but (in equal temperament) indistinguishable audibly from those spelled in the appropriate way. Here, the perverse spelling (whether humorous or annoying to the trained continuo player) is not unusual graphically, but represents a score writing unmotivated except as an inside joke between composer and performer, and is unhearable by the listener.

The ''Gulliver Suite'' by Telemann discussed below, shows a combination of three eye music features. The score is made difficult "unnecessarily," is eye-catching for its graphics, and has a clever external reference, all unnoticeable to the listener.

The Renaissance

Two examples of eye music from the early Renaissance are from Baude Cordier (ca. 1380-ca.1440). Cordier's chanson about love ''Belle, bonne, sage'' is in a heart shape, with red notes ( coloration) indicating rhythmic alterations. Eye-music-within-eye music is in the small group of notes hanging like a locket in the upper left, also all in red and in the shape of a heart. Another work of Cordier, this time inscribed in circles, ''Tout par compas suy composés'' ("With a compass was I composed"), goes out of its way to identify itself as eye music.

Josquin des Prez, the most important composer of the next generation, used black note notation eye music in his well-known ''Nymphes des bois,'' a lament over the death of the composer Ockeghem, as well as another lament, this time for the composer Jacob Obrecht, ''Absolve, quaesumus, Domine.''

It can be seen that words of death and lament are associated with black notes, a mannerism made even simpler to achieve in light of the contemporaneous simplification to white note notation. This feature of eye music would extend through the Humanist period.

Another instance of eye music in the Renaissance is apparently unique—the representation of a triangle for a canonic piece, which appears in juxtaposition with an anonymous canon written in a circle—in Dosso Dossi's ''Allegory of Music.'' (It has been suggested that both the technique of canon itself as well as its representation—the circle and the inherent symbolism of the tenets of Christianity in the triangle—also imply a "sense of the infinite.") The work represented in the triangle, is part of a "rough" version of a puzzle canon in Josquin's Agnus Dei II from his ''Missa L'homme armé super voces musicales'' canonic mass. It has the superscript "trinitas in un m ("three in one") as a clue to its solution, is a mensuration canon of 3:1, and has one voice take part at the interval of a fifth, that is, 3:2. Its relation to the Christian Holy Trinity is clear, suggesting the use of a triangular representation. The representation is unique, although possibly from a copy used by Dossi.

Humanism

With the significant shift of style of composers of the Humanist movement—the rediscovery and translation of Greek texts in the mid-16th century—eye music flourished. The change in musical practice, particularly with the madrigalists and their focus on text declamation, at a word-by-word basis, was fertile ground for eye music. Words that suggest "blackness," such as "death" or "night," receive "black" notes (e.g. quarter notes, eighth notes); "white words" such as "light" or "pale" receive "white" notes (e.g. whole notes, half notes).Einstein, Alfred. "Augenmusik im Madrigal." ''Zeitschrift für internationazional Musikgesellschaft,'' XIX (1912–13), pp. 8–21; partly trans. in The Italian Madrigal, transl. Krappe, Sessions, and Strunk. 3 Vol. Princeton:Princeton University Press, (1949) 1971.

With the Italian madrigalists from the 1580s until the early 17th century (whose style was almost literally imported to England), eye music reached its apogee until its transformation in the 20th century.''See'' Einstein, Alfred. The Italian Madrigal, transl. Krappe, Sessions, and Strunk. 3 Vol. Princeton:Princeton University Press, (1949) 1971. Luca Marenzio is considered the composer most fond of eye music. For example, in the madrigal ''Senza il mia sole'' from his ''Madrigali a quattro, cinque e sei voci'' (1588), black notes are used for "chiuser le luci" ("close their eyes")

Reaction by theorists of the time was mixed. A leading musical humanist, Vincenzo Galilei (the father of the physicist), was opposed to it but Zarlino approved. In the 20th century, Alfred Einstein, a groundbreaking scholar of the Humanist madrigal, wrote that eye music is "the most extreme and (for our aesthetic convictions) most horrible testimony of naturalism, of ''imitazione,'' in the madrigal."

Baroque

In Telemann's ''Gulliver Suite'' for two violins the note values in the chaconne are " Lilliputian", and, in the gigue, are "Brobdingnagian" ones. Because the Lilliputian movement is written in the bizarre time signature of , and the Brobdingnagian one in the equally obtuse (which is doubly humorous because gigues are generally light and brisk), the time signatures reduce to and , perfectly normal ones for each movement, as are the tempos associated with them and the type of dance of each.

20th century

Post-tonal music has seen an expansion of eye music in line with its expansion and experimentalism of musical techniques. The last examples using a rigorous scoring system rooted in standard practice are the finely turned circles and spirals (as well as a peace symbol and a crucifix) in the works of George Crumb.

Graphic notation

The beauties of many examples of graphic notation are not, in fact, a feature of eye music. As novel and attractive as the graphics may be in these scores, they function entirely as performance indications or true records of compositional method (such as the Steiner score shown here). Also often seen are graphical or conceptual art works that use the symbols of music notation but are not performing scores at all, such as Erwin Schulhoff's 1919 ''In futurum (Zeitmaß-zeitlos)''Third movement of and Cornelius Cardew's Treatise.
