On 30 December 1735, Ferdinand Zellbell’s father wrote to Carl Gustaf Tessin about his sixteen-year-old son. Ferdinand Zellbell could already play figured bass—a system in which numbers below a bass line guide the player in supplying harmonies—and had substituted at the organ of Stockholm’s Storkyrkan. He used both the manuals, or hand keyboards, and the pedal keyboard.
The letter sought support for study abroad, but that journey did not take place at the time. Ferdinand Zellbell instead continued his training in Sweden before studying with Johan Roman and, later, Georg Telemann. He would eventually teach Olof Åhlström at the Royal Swedish Academy of Music.
The direction of these relationships is clear: Johan Roman and Georg Telemann taught Ferdinand Zellbell; Ferdinand Zellbell taught Olof Åhlström. The evidence for what happened in the lessons is less complete.
Training before Hamburg
Born in Stockholm in 1719, Ferdinand Zellbell first studied with his father. Abraham Hülphers’s eighteenth-century account identifies the elder Zellbell as a teacher, though no lesson book or exercise connected with the father and son has been found.
The 1735 letter shows that Ferdinand Zellbell was already a working organist rather than a beginner. His command of figured bass also gave him experience in continuo, the bass line and improvised harmony that supported much eighteenth-century ensemble music. Any later instruction from Johan Roman or Georg Telemann therefore built on practical keyboard training.
Ferdinand Zellbell’s estate shows what kinds of books and instruments remained available to him later. His library included Johann Mattheson’s Critica Musica and Der vollkommene Capell-Meister, Carl Philipp Emanuel Bach’s Versuch über die wahre Art das Clavier zu spielen, and theoretical works by Friedrich Wilhelm Marpurg. He also owned writings on tuning by Andreas Werckmeister.
His instruments included a large keyboard, a smaller keyboard fitted into a music stand, and a pedal keyboard. This equipment could support organ teaching outside a church, but it does not show what Ferdinand Zellbell taught in any particular lesson.
Georg Telemann teaches composition
The strongest evidence that Ferdinand Zellbell studied with Georg Telemann comes from an undated letter written by Johan Miklin to Abraham Hülphers. Miklin reported that Ferdinand Zellbell went to Hamburg and spent several months with Georg Telemann.
Ferdinand Zellbell learned from Georg Telemann “the laws of composition.”
Miklin belonged to Ferdinand Zellbell’s professional world, but he was also an opponent whose judgments were not impartial. His report remains useful because it names the teacher and place, gives an approximate duration, and identifies the subject. It appears to be second-hand, however, and no evidence shows that Miklin witnessed the lessons.
MusicLineage dates Ferdinand Zellbell’s Lower Saxon studies to 1739–1741. Current Swedish biographical work uses the same period and places him with Georg Telemann in Hamburg. An earlier study gives 1741–1742, but Miklin’s phrase “several months” does not settle the difference.
No correspondence between Georg Telemann and Ferdinand Zellbell has been found. Nor has a Hamburg pupil register, a lesson exercise, or a testimonial signed by Georg Telemann. The surviving evidence establishes formal study in composition more securely than it establishes an exact timetable.
Can the lessons be heard in Ferdinand Zellbell’s music?
Ferdinand Zellbell composed the cantata Auf Zion, auf for the consecration of the Stückhoff church in Saint Petersburg on 8 November 1758. Its scoring and orchestral response to the text place it in a Protestant cantata practice associated with Georg Telemann.
That connection does not identify a device learned in Hamburg. The surviving material is too limited to measure Georg Telemann’s influence on the work, and Auf Zion, auf contains no annotation linking it to a lesson. It provides material for comparison, not proof of a particular act of teaching.
Johan Roman and the Swedish pupil circle
After the proposed journey of 1735 failed, Ferdinand Zellbell continued studying in Sweden. Swedish biographical authorities place him among Johan Roman’s pupils, and Tobias Norlind’s 1918 history identifies composition as the subject.
The relationship is consistent across later biographical accounts, but its archival basis is thin. No letter from Johan Roman naming Ferdinand Zellbell as a student has been found. There is also no dated pupil list or surviving composition exercise corrected by Johan Roman.
A later event gives the connection a documented musical result. On 30 May 1767, Ferdinand Zellbell directed a memorial concert for Johan Roman, who had died in 1758. Music lovers and members of the Royal Court Orchestra performed Johan Roman’s compositions under Ferdinand Zellbell’s direction.
The concert does not independently prove that lessons took place. It does show that Ferdinand Zellbell selected, rehearsed, and conducted Johan Roman’s music after his teacher’s death. This is firmer evidence of repertory passing between generations than a general resemblance between their compositions.
Ferdinand Zellbell’s earliest known surviving cantata, Befalla Herranom tin wäg, dates from 1750 and is preserved in a manuscript considered probably autograph. It sets Psalm 37 as a duet for two sopranos, two violins, and continuo. The scoring belongs to late-Baroque practice familiar in Johan Roman’s Stockholm, but the manuscript contains no reference to his teaching.
An overture for strings from 1742 has also been described as Scarlattian in manner. That description does not show that Johan Roman served as the intermediary. The dates and contents of his lessons with Ferdinand Zellbell remain unknown.
Olof Åhlström enters the Academy
The connection between Ferdinand Zellbell and Olof Åhlström can be placed within a particular institution. Olof Åhlström, born in Vårdinge parish in Södermanland in 1756, came to Stockholm in 1772. He entered the Royal Swedish Academy of Music’s teaching establishment as Ferdinand Zellbell’s organ student.
Ferdinand Zellbell had been chosen to direct the Academy’s educational work on 31 December 1771. He helped manage its statutes and teaching programme, but the institution soon faced financial trouble. About two years after its foundation, a letter reported that the treasury was empty and that the teaching establishment might have to close.
It did close in 1774. Ferdinand Zellbell appears to have continued teaching Olof Åhlström privately, though the available source presents this as probable rather than certain.
Organ playing is the documented subject. A later biographical dictionary says that private study with Ferdinand Zellbell also introduced Olof Åhlström chiefly to music by Gluck and Haydn. No dated lesson list or annotated edition has been found to confirm that repertory claim.
Olof Åhlström became organist at Maria Church in 1776 and later served at Jakob Church. Contemporary accounts praised his organ improvisation, the practice of creating music during performance rather than playing a fully written work. His appointments fit the chronology of successful organ training, but they do not divide his skills between Ferdinand Zellbell’s lessons, earlier local instruction, and later experience.
The same limit applies to Olof Åhlström’s compositions and publications. His Trois sonates pour le clavecin, songs, editions of Bellman, and 1832 chorale book belong to a career that continued long after Ferdinand Zellbell’s death in Stockholm in 1780. No surviving source connects a passage in any of those works to a correction or exercise by Ferdinand Zellbell.
Olof Åhlström later followed his teacher into the Academy’s administration. He was elected to the institution in 1785 and directed its teaching establishment from 1803 to 1805. The succession of offices is documented, though no source says that he consciously copied Ferdinand Zellbell’s methods.
Patrik Alströmer and the means to work
Teaching depended on money, instruments, rooms, and performers. Patrik Alströmer helped Ferdinand Zellbell secure those resources. In a surviving letter, Ferdinand Zellbell called him a benefactor and thanked him for repeated help during a financial crisis.
A contemporary report states that Ferdinand Zellbell travelled to Saint Petersburg with Patrik Alströmer and at his expense. During that visit, Ferdinand Zellbell produced the opera Il giudizio d’Aminta as well as Auf Zion, auf.
Their work together continued in Stockholm. Patrik Alströmer performed as one of the aristocratic amateurs in the cavalier concerts that Ferdinand Zellbell conducted at the House of Nobility. A contemporary report described an orchestra of more than fifty professional and amateur players. Complete programmes have not survived, so the repertory cannot be reconstructed.
Correspondence between the two men also discusses the Academy’s empty treasury and unpaid teaching. Patrik Alströmer’s place in Ferdinand Zellbell’s network rests on documented finance, travel, performance, and institutional business rather than a teacher-pupil relationship.
Other pupils in Stockholm
The singer Elisabet Lillström-Olin and her father, the court musician and Katarina Church organist Peter Lillström, also studied with Ferdinand Zellbell. Elisabet Lillström-Olin later sang as a soloist in every documented cavalier concert covered by the surviving account.
This places her training within Ferdinand Zellbell’s concert work, but no vocal exercises or scores bearing his annotations have been located. These pupils have not received the same archival study as Olof Åhlström, whose Academy entry supplies a firm date and subject.
The remaining uncertainty begins with chronology: MusicLineage places Ferdinand Zellbell’s Lower Saxon studies in 1739–1741, whereas an earlier study gives 1741–1742. An undated letter cannot choose between them. Until correspondence, a pupil register, or an instructional manuscript appears, neither Georg Telemann’s exact lesson dates nor the contents of Johan Roman’s teaching can be fixed, and no corrected manuscript yet connects Ferdinand Zellbell’s instruction to a specific passage by Olof Åhlström.
