Jean-Adam Guilain (whose German birth name was Johann Adam Wilhelm Freinsberg) (c. 1680 – after 1739) was a German organist and harpsichordist who relocated to France some time before 1702. He was active in Paris during the first half of the eighteenth century.
Guilain was born in Germany, (the exact dates of birth and death are unknown). He was almost certainly one of Louis Marchand's pupils - Guilain's organ collection is dedicated to Marchand, by then a prominent organ teacher. Guilain died some time after 1739, the year when he published a collection of harpsichord pieces. Although he came from Germany, Guilain's musical style appears to be in the pure French tradition. He was apparently for a time organist of Saint-Honoré in Paris.
The Tierce en Taille recorded here is from the Suite du Second ton. I have not felt uncomfortable recording this piece using the Rotterdam sample set because of its very fine mounted Cornet which beautifully sings the melody. I've used the French "Ordinaire" temperament for this recording.
