Here is an Allegory of Music by Laurent de la Hyre (+1656).
The figure is playing a theorbo, or chitarrone, probably a symbol of musica “artificiale“. They had drone strings and produced a rather symphonic effect. On the other hand, the little bird is probably a symbol of musica “naturale“.
And simply because she is so beautiful.
Thank you Filippino Lippi!
For St Ambrose on his feast!
By Giovanni di Paolo.
By the way, we don’t know what exact piece is in the manuscript in the painting. However, so that you know more about the theorbo, here is a great video that shows it from many angles.
The being played is by Kapsberger, who did in 1651 in Rome. The painting is from 1647.
And this piece, with a touch in Piccinini, is a little more groovy.
