Context and sources

Information on Guido's life is scarce; the music historian Charles Burney asserted that the paucity of records was because Guido was a monk. Burney furthered that, in the words of musicologist Samuel D. Miller, "Guido's modesty, selfless abandon from material gain life, and obedience to authority tended to obscure his moves, work, and motivations". The scholarly outline of Guido's life has been subject to much mythologization and misunderstandings. These dubious claims include that he spent much of life in France (recorded as early as

near Paris; and unsupported rumours that he was imprisoned because of plots from those hostile to his innovations. The primary surviving documents associated with Guido are two undated letters; a dedicatory letter to Bishop Tedald of Arezzo and a letter to his colleague Michael of Pomposa, known as the ''Epistola ad Michaelem''. These letters provide enough information and context to map the main events and chronology of Guido's life, though Miller notes that they do "not permit a detailed, authoritative sketch".


Life and career


Early life

Guido was born sometime between 990 and 999. This birthdate range was conjectured from a now lost and undated manuscript of the '' Micrologus'', where he stated that he was age 34 while John XIX was

(1024–1033). Swiss musicologist dating of the manuscript to 1025–1026 is agreed by scholars Claude V. Palisca, Dolores Pesce and Angelo Mafucci, with Mafucci noting that it is "now unanimously accepted". This would suggest a birthdate of . Guido's birthplace is even less certain, and has been the subject of much disagreement between scholars, with music historian Cesarino Ruini noting that due to Guido's pivotal significance "It is understandable that several locations in Italy claim the honor of having given birth to G ido. There are two principal candidates:

'of Arezzo' is because of his stay of about a dozen years there later in life. Disagreeing with Van Waesberghe's conclusions, Mafucci argued that were Guido born in Pomposa, he would have spent nearly 35 years there and would thus more likely be known as 'of Pomposa'. Mafucci cites the account of the near-contemporary historian Sigebert of Gembloux (–1112) who referred to Guido as "Guido Aretinus" (Guido of Arezzo), suggesting that the early use of such a designation means Guido's birthplace was Arezzo. Citing recently unearthed documents in 2003, Mafucci identified Guido with a ''Guido clerico filius Roze'' of the Arezzo Cathedral. If Mafucci is correct, Guido would have received early musical education at the Arezzo Cathedral from a

Pomposa

Around 1013 Guido went to the Pomposa Abbey, one of the most famous

, he started to develop the novel principles of staff notation (music being written and read from an organized visual system). Likely drawing from the writings of , Guido began to draft his system in the antiphonary ''Regulae rhythmicae'', which he probably worked on with his colleague Michael of Pomposa. In the prologue to the antiphonary, Guido expressed his frustration with the large amount of time singers spent to memorize music. The system, he explained, would prevent the need for memorization and thus permit the singers extra time to diversify their studies into other prayers and religious texts. He began to instruct his singers along these lines and obtained a reputation for being able to teach substantial amounts of music quickly. Though his ideas brought interest from around Italy, they inspired considerable jealousy and resistance from his fellow monks, who felt threatened by his innovations. Among those disapproving was the

. In light of these objections, Guido left Pomposa in around 1025 and moved to—or 'returned to', if following the Arezzo birthplace hypothesis—Arezzo.


Arezzo, Rome and later life

Arezzo was without a monastery; Bishop Tedald of Arezzo (Bishop from 1023 to 1036) appointed Guido to oversee the training of singers for the Arezzo Cathedral. It was at this time that Guido began work on the ''Micrologus'', or in full ''Micrologus de disciplina artis musicae''. The work was both commissioned by and dedicated to Tedald. It was primarily a musical manual for singers and discussed a wide variety of topics, including chant, polyphonic music, the monochord,

Theobald may have helped arrange the visit, and in around 1028, Guido traveled there with the Canon Dom Peter of Arezzo as well as the Abbot Grimaldus of Arezzo. His presentation incited much interest from the

and the details of his visit are included in the ''Epistola ad Michaelem''. While in Rome, Guido became sick and the hot summer forced him to leave, with the assurance that he would visit again and give further explanation of his theories. In the ''Epistola ad Michaelem'', Guido mentions that before leaving, he was approached by the Abbot Guido of Pomposa who regretted his part in Guido's leave from Arezzo and thus invited him to return to the Abbey. Guido of Pomposa's rationale was that he should avoid the cities, as most of their churchmen were accused of simony, though it remains unknown if Guido chose the Pomposa Abbey as his destination. It seems more likely that around 1029, Guido settled in a monastery of the Avellana of the Camaldolese order near Arezzo, as many of the oldest manuscripts with Guidonian notation are Camaldolese. The last document pertaining to Guido places him in Arezzo on 20 May 1033; his death is only known to have been sometime after that date.


Music theory and innovations


Works

Four works are securely attributed to Guido: the ''Micrologus'', the ''Prologus in antiphonarium'', the ''Regulae rhythmicae'' and the ''Epistola ad Michaelem''. The ''Epistola ad Michaelem'' is the only one not a formal musical treatise; it was written directly after Guido's trip to Rome, perhaps in 1028, but no later than 1033. All three musical treatises were written before the ''Epistola ad Michaelem'', as Guido mentions each of them in it. More specifically, the ''Micrologus'' can be dated to after 1026, as in the preliminary dedicatory letter to Tebald, Guido congratulates him for his 1026 plans for the new St Donatus church. Though the ''Prologus in antiphonarium'' was begun in Pomposa (1013–1025), it seems to have not been completed until 1030.


Solmization

Guido developed new techniques for teaching, such as staff notation and the use of the "ut–re–mi–fa–sol–la" (do–re–mi–fa–so–la)
mnemonic A mnemonic device ( ), memory trick or memory device is any learning technique that aids information retention or retrieval in the human memory, often by associating the information with something that is easier to remember. It makes use of e ...
( solmization). The syllables ut-re-mi-fa-sol-la (do-re-mi-fa-sol-la) are taken from the six half-lines of the first stanza of the hymn " Ut queant laxis", the notes of which are successively raised by one step, and the text of which is attributed to the Italian monk and scholar Paulus Deacon (although the musical line either shares a common ancestor with the earlier setting of Horace's Ode to Phyllis (Odes 4.11) recorded in Montpellier manuscript H425, or may have been taken from there).Stuart Lyons, ''Horace's Odes and the Mystery of Do-Re-Mi with Full Verse Translation of the Odes''. Oxford: Aris & Phillips, 2007. Giovanni Battista Doni is known for having changed the name of note "Ut" (C), renaming it "Do" (in the "Do Re Mi ..." sequence known as

) was added shortly after to complete the diatonic scale. In anglophone countries, "Si" was changed to "Ti" by Sarah Glover in the nineteenth century so that every syllable might begin with a different letter (this also freed up Si for later use as Sol-sharp). "Ti" is used in tonic sol-fa and in the song " Do-Re-Mi".


The Guidonian hand

Guido is somewhat erroneously credited with the invention of the
Guidonian hand The Guidonian hand was a mnemonic device used to assist singers in learning to sight reading, sight-sing. Some form of the device may have been used by Guido of Arezzo, a medieval music theory, music theorist who wrote a number of treatises, incl ...

s cannot be securely attributed to him. In the 12th century, a development in teaching and learning music in a more efficient manner arose. Guido of Arezzo's alleged development of the Guidonian hand, more than a hundred years after his death, allowed musicians to label a specific joint or fingertip with the

(also referred to as the hexachord in the modern era). Using specific joints of the hand and fingertips transformed the way one would learn and memorize solmization syllables. Not only did the Guidonian hand become a standard use in preparing music in the 12th century, its popularity grew more widespread well into the 17th and 18th centuries. The knowledge and use of the Guidonian hand would allow a musician to simply transpose, identify intervals, and aid in the use of notation and the creation of new music. Musicians were able to sing and memorize longer sections of music and counterpoint during performances and the amount of time spent diminished dramatically.


Legacy

Almost immediately after his death commentaries were written on Guido's work, particularly the ''Micrologus''. One of the most noted is the ''De musica'' of Johannes Cotto (), whose influential treatise was largely a commentary that expanded and revised the ''Micrologus''. Aribo () also dedicated a substantial part of his ''De musica'' as a commentary on chapter 15 of the ''Micrologus''. Other significant commentaries are anonymous, including the ''Liber argumentorum'' and ''Liber specierum'' (both Italian, 1050–1100); the ''Commentarius anonymus in Micrologum'' (Belgian or Bavarian, ); and the ''Metrologus'' (English, 13th century). Guido of Arezzo and his work are frequent namesakes. The controversial

''Missa Scala Aretina'' (1702) by Francisco Valls takes its name from Guido's hexachord. Lorenzo Nencini sculpted a statue of Guido in 1847 that is included in the Loggiato of the Uffizi, Florence. A statue to him was erected 1882 in his native Arezzo; it was sculpted by Salvino Salvini. Modern namesakes include the computer music notation system GUIDO music notation, as well as the "Concorso Polifónico Guido d'Arezzo" (International Guido d'Arezzo Polyphonic Contest) hosted by the Fondazione Guido D'Arezzo in Arezzo.
