On this website I am giving insights into my musicological activities – mainly devoted to the research of Irish musical history. I am active in this area since my academic year in Dublin, way back in 1987–8.


Another field of interest which is regaining significance for me is the history of the classical guitar – my instrument for some 40 years now. In fact, my very first academic articles in the early 1990s were devoted to the guitar.


Have a look around - and if you have a question let me know.

6 October 2021: I have currently five articles in the publication pipeline, in three languages and with publishers in five countries (Ireland, England, France, Germany, Belgium). Long live Europe!

September 2021: I went to Poznan in Poland to witness the recordings of the next CD with music by Swan Hennessy, with Marcin Murawski (viola) and Hanna Holeksa (piano). Fantastic musicians, and a recording worth looking out for.


July 2020: I am the co-producer of a CD with selected music for piano by Swan Hennessy – all world premiere recordings! It has been recorded 3–5 July by Moritz Ernst and will be published later this year (hopefully) on the Perfect Noise label.

April 2019: As part of my uncovering of the music of Swan Hennessy (1866–1929), the first ever release of a CD devoted to his music has just occurred: His complete string quartets and a 1921 string trio have appeared on RTÉ lyric fm CD 159, performed by the RTÉ ConTempo Quartet. My job(s): researching Hennessy and the music, convincing the musicians to try it, convincing RTÉ to invest in it, writing the booklet notes.


September 2018: I am giving a Musicology Seminar at University College Dublin (UCD) on 20 September.


June 2018: Returned from a few days in southern Normandy (France) where I saw (and received on loan) a number of further manuscripts, prints, photographs, etc. of Swan Hennessy that are in a country house of the family. It is a privilege to work with such material.


July 2017: I seem to be increasingly in demand for writing programme notes to concerts and liner notes for CD booklets. I just finished notes for string quartets by Ina Boyle (1934) and Brian Boydell (1949) for the next season of the RTÉ ConTempo Quartet. And just appeared is a CD with chamber music by Rhona Clarke (b. 1958) (Métier MSV 28561) to which I wrote an introductory essay. Next up is an essay on 'Celticism in Irish Opera' for the programme booklet to the concert performance of Robert O'Dwyer's opera 'Eithne' (1909) in Dublin on 14 October 2017.


November 2016: Returned from some exciting days in Ireland in relation to my research on the Irish-American composer Swan Hennessy (1866–1929): First, an interview with the 'Irish Examiner' (31 October), see online here; second, a live interview on RTÉ Radio 1's ARENA Arts Show (3 November), listen to podcast here; third, a pre-concert talk on Hennessy's String Quartet No. 2, Op. 49 (1920) at Triskel Arts Centre, Cork (5 November).

September 2014: My O'Kelly book was featured in the blog of the American Musicological Society where it was welcomed for its "newfangled, dare we suggest paradigmatic?, ways Klein's book was researched and published". See for yourself here.


May 2014: My new book has appeared in print and as an e-book: O'Kelly - An Irish Musical Family in Nineteenth-Century France (Norderstedt: BoD, 2014).


March 2014: I was involved in a rare Saint Patrick's Day event in Frankfurt, Germany, where the Junge Sinfoniker Frankfurt played early Irish music by John Sigismond Cousser (1660-1727), Matthew Dubourg (1703-1767), Thomas Augustine Geary (1775-1801) and Paul Alday (1763-1835). I suggested some of this repertory and helped to find some of the scores.


March 2013: I received seven (!) original scores of piano music by Joseph O'Kelly from the antiquarian music seller Philippe Cabarat. They are Reverie d'automne op. 12 (1857), Au bord de la mer op. 19 (1860), La Bruyère op. 22 (1862), La Noce de village op. 34 (1868), La Retraite op. 35 (1868), Au bal op. 51 (1875), and À l'aventure op. 65 (1884). Earlier this month my collection was also enhanced by some pieces I received from England. Among them were a song by Michael Kelly: In the Rough Blast Heaves the Billow (c1802) and John Field's Rondeaux No. II (c1817).


January 2013: A 6-part broadcast series at Irish radio station RTÉ Lyric FM called "Women of Note" is downloadable from the station's website. It was broadcast between September and December 2012. You can hear me in each of the six parts, as I was interviewed for it last year in Frankfurt.


November 2012: Received a rare copy of the very first piano composition by George O'Kelly, the Nocturne from Deux Pensées Charactéristiques published 1853 in Boulogne-sur-mer (from the antiquarian dealer Paul van Kuik).


September 2012: I was the first musicologist to have looked through the sheet music collection of the Princess Grace Irish Library in Monaco. In this capacity I was asked to write a short assessment of the collection to be archived together with the music.
