Editing Constantijn Huygens (section)

===Music education===
They started with singing lessons, and they learned their notes using gold-coloured buttons on their jackets. It is striking that Christiaan senior imparted the "modern" system of 7 note names to the boys, instead of the traditional, but much more complicated [[hexachord]] system. Two years later the first lessons on the viol started, followed by the lute and the harpsichord. Constantijn showed a particular acumen for the lute. At the age of eleven he was already asked to play for ensembles, and later—during his diplomatic travels—his lute playing was in demand; he was asked to play at the Danish Court and for [[James I of England]], although they were not known for their musical patronage. In later years he also learnt the more modern guitar. In 1647 he published in Paris his ''Pathodia sacra et profana'' with his compositions of [[airs de cour]] in French, [[madrigals]] in Italian and Psalms in Latin.{{Citation needed|date=May 2025}}
