In 1637, the Viennese court granted 200 gulden after Johann Froberger asked to be sent “to Rome to Frescobaldi.” A further entry records that he received 100 gulden for the journey on 25 September. These administrative records were made before the proposed study and name Girolamo Frescobaldi as its purpose.
A pedagogical lineage is a sequence of named teachers and students. Such a sequence can extend across centuries in a database, but its links may rest on different kinds of evidence: a payment made before lessons, a student’s statement, a late biography or a similarity between compositions. The ten-generation network around Girolamo Frescobaldi contains all of these, and several links do not withstand the same scrutiny as the 1637 Viennese record.
Johann Froberger in Frescobaldi’s household
A letter written in Rome on 24 April 1638 confirms that the proposed study took place. Scipione Gonzaga, the imperial ambassador, told Emperor Ferdinand III that Johann Froberger had been sent to learn harpsichord playing. He had converted to Catholicism and moved into Girolamo Frescobaldi’s house so that he could work more closely. Girolamo Frescobaldi himself reported that his student was making substantial progress.
The letter establishes the setting and subject of the instruction without relying on later musical analysis.
Johann Froberger had moved into Girolamo Frescobaldi’s house and was making substantial progress under him.
A Roman parish entry from 1640 records a “Gio. Jacomo tedesco,” or “Giovanni Giacomo the German,” whom Claudio Annibaldi identified as Johann Froberger. Johann Froberger had returned to imperial service in Vienna by April 1641.
This is the strongest student link in Girolamo Frescobaldi’s international network. The 1637 records show the court authorising and funding the journey; the 1638 letter reports the living arrangement and Girolamo Frescobaldi’s assessment of the student. No comparable contemporary evidence has been found for Johann von Kerll or Franz Tunder.
The documents specify harpsichord playing, but they do not preserve a syllabus. Comparisons between Johann Froberger’s early keyboard works and Roman manuscripts associated with Girolamo Frescobaldi’s circle can show musical transmission. They cannot identify particular exercises, conversations or assigned compositions.
The documented line before Frescobaldi
The strongest link immediately before Girolamo Frescobaldi is Luzzasco Luzzaschi → Girolamo Frescobaldi. In the dedication to his Capricci of 1624, Girolamo Frescobaldi described the musical work of his youth as undertaken:
“under the discipline” of Luzzasco Luzzaschi.
This is the student naming his own teacher, rather than a biographer reconstructing the relationship from their music.
The preceding Cipriano de Rore → Luzzasco Luzzaschi link also rests on a first-person statement. In a 1606 letter to Cardinal Federico Borromeo, Luzzasco Luzzaschi called himself Cipriano de Rore’s disciple. He also described possessing his teacher’s compositional cartella, a tablet or board used for drafting music. Luzzasco Luzzaschi sent the object to Cardinal Federico Borromeo, and it entered the Biblioteca Ambrosiana.
The resulting documented core is:
Cipriano de Rore → Luzzasco Luzzaschi → Girolamo Frescobaldi → Johann Froberger
The MusicLineage route continues backward through Adrian Willaert, Jean Mouton, Josquin des Prez, Johannes Ockeghem and Gilles Binchois. It reaches seven steps above Girolamo Frescobaldi, but the evidence is not uniform.
A Venetian title page from 1549 called Cipriano de Rore Adrian Willaert’s discepolo, meaning disciple or follower. No surviving record establishes lessons or service under Adrian Willaert. Farther back, later writers described Josquin des Prez as a pupil of Johannes Ockeghem, but no evidence of that education survives. Nymphes des bois, Josquin des Prez’s lament for Johannes Ockeghem, shows commemoration and respect, not formal study by itself.
The upstream route therefore combines direct testimony with labels whose meaning remains uncertain.
Johann von Kerll and the missing Roman lessons
MusicLineage records Girolamo Frescobaldi → Johann von Kerll, but the available documents identify different teachers. Johann von Kerll’s training under Giovanni Valentini in Vienna and Giacomo Carissimi in Rome has firmer support. Johann Gottfried Walther’s Musikalisches Lexicon of 1732 reports that Archduke Leopold Wilhelm sent Johann von Kerll to study composition with Giacomo Carissimi at Sant’Apollinare.
Athanasius Kircher’s Musurgia universalis of 1650 printed a Toccata sive Ricercata by Johann von Kerll, placing his music within the Roman intellectual setting. It does not connect him to lessons with Girolamo Frescobaldi.
Chronology makes the traditional claim difficult. Girolamo Frescobaldi died in 1643. The most plausible reconstruction places Johann von Kerll in Vienna during the early 1640s, at the Brussels court by 1647, and in Rome around 1648–50. His documented Roman period would therefore fall after Girolamo Frescobaldi’s death.
Johann von Kerll’s keyboard music shows knowledge of an Italian tradition associated with Girolamo Frescobaldi. His surviving repertory includes eight toccatas, six canzonas, a ciaccona, a passacaglia and the 56 Magnificat versets published as Modulatio organica in 1686. These works cannot identify who transmitted that musical language. Printed music, manuscripts, Johann Froberger and other musicians in the Roman–German network remain possible channels.
Johann von Kerll’s study with Girolamo Frescobaldi is unestablished and chronologically doubtful.
Franz Tunder and Johann Mattheson’s late account
The claim that Girolamo Frescobaldi taught Franz Tunder can be traced to Johann Mattheson’s Grundlage einer Ehren-Pforte, published in Hamburg in 1740. The book appeared seventy-three years after Franz Tunder’s death and nearly a century after the proposed lessons.
Later accounts placed Franz Tunder in Italy or Florence, sometimes in connection with Johann Heckelauer. Girolamo Frescobaldi worked at the Medici court in Florence from 1628 to 1634, so a meeting was possible in principle. No travel record, payment, letter, parish entry or household document has been found to place Franz Tunder there.
Modern accounts have also suggested that Johann Mattheson confused Franz Tunder with Johann Heckelauer, his predecessor at the Gottorf court. Franz Tunder’s organ music may reflect contact with Italian keyboard repertory, but such contact did not require personal instruction. Prints and manuscripts could travel without their composers.
The proposed apprenticeship remains a late and unreliable tradition, not a documented teacher–student relationship.
The break between Johann von Kerll and Wolfgang Prentz
MusicLineage also records Johann von Kerll → Wolfgang Prentz. Wolfgang Prentz’s autobiographical account, published in his Historische Beschreibung der edelen Sing- und Kling-Kunst of 1690, names a substantial group of teachers and professional contacts. His early teachers included Kilian Hammer, Wilhelm Stöckel and Andreas Pauli von der Heyd. In Weiden he worked with Wolfgang Altus, Johann Konrad Mertz and Johann Georg Schober.
The account follows his travels through Germany and Italy, his arrival in Dresden in 1662 and his meeting with Franciscus Santi, who recommended him for employment with Count Erdmann Leopold von Promnitz. It later records travel through Austria and Vienna. Johann von Kerll does not appear as a teacher or formative contact.
An autobiographical omission cannot prove that two musicians never met. In this case, however, the absence matters because Wolfgang Prentz named several less prominent teachers. No lesson book, letter, dedication, employment overlap or contemporary biography has been found to connect him pedagogically with Johann von Kerll.
What the ten-generation graph reaches
If every MusicLineage teacher arrow is accepted, one downstream route runs from Girolamo Frescobaldi through Johann von Kerll, Wolfgang Prentz, Johann Pachelbel and Johann Christoph Bach to Johann Sebastian Bach. It then divides into several branches.
Through Gottfried Homilius, Daniel Türk and Adolf Marx, the graph reaches Nikolai Zaremba at nine generations. At the tenth generation it includes Pyotr Tchaikovsky, Vladimir Pukhalsky, Vasily Safonov, Nikolai Soloviev and Karl van Ark. Another route from Adolf Marx reaches Karl Barth and then Heinrich Neuhaus, Erwin Bodky, Wilhelm Kempff and Arthur Rubinstein. A separate branch passes from Johann Sebastian Bach through Johann Trier, Johann Schicht, Karl Becker and Robert Volkmann to Istvan Thoman.
These are valid descriptions of the graph’s structure, but they are not equivalent to a documented ten-generation Frescobaldi school. Both Girolamo Frescobaldi → Johann von Kerll and Johann von Kerll → Wolfgang Prentz lack supporting evidence, so the route breaks before it reaches Johann Pachelbel.
Music travelled where pedigrees fail
Girolamo Frescobaldi’s music reached Johann Sebastian Bach without requiring an uninterrupted classroom chain. A manuscript of Fiori musicali carried the inscription “J. S. Bach 1714.” The manuscript was lost during the Second World War. It appears to have been a scribal copy on which Johann Sebastian Bach added his name and date, rather than necessarily a complete autograph in his hand. Even under that qualification, it documents his possession and study of a specific Girolamo Frescobaldi edition.
Johann von Kerll also reached Johann Sebastian Bach through a surviving composition. Johann Sebastian Bach arranged the Sanctus from Johann von Kerll’s Missa superba as BWV 241. That work-to-work connection is direct evidence of reception, though it cannot prove that Johann von Kerll studied with Girolamo Frescobaldi.
The unresolved point in the strongest relationship is narrower but still substantial: no document identifies what Girolamo Frescobaldi taught Johann Froberger beyond harpsichord playing. Until a lesson book or annotated manuscript appears, particular toccatas, ricercars and counterpoint exercises cannot be assigned to their Roman lessons.
