Luigi Lera has a Degree in Humanities and a Diploma in Pianoforte and Choral Music. He holds the Chair of Music History at Udine Conservatory of Music. He has published works on mediaeval teaching methods, on polyphony from its origins and on contrapuntal technique. He has edited music by Jacques Arcadelt, Giovanni Maria Asola and Andrea Gabrieli, and is the author of a manual of Gregorian Chant, a volume dealing with Musical Acoustics (in collaboration with the physicist Vincenzo Schettini) and a teaching method for Harmony and Counterpoint. He has recorded mediaeval liturgical music, fourteenth-century Italian polyphony, and Renaissance madrigals. Since 2012 he has been running the website www.tmpol.it devoted to the polyphonic repertoire: here you can find the transcriptions and the audio tracks of over two hundred compositions from various periods and in various styles, realised with the use of specific criteria according to the differing characteristics of different periods in history.
