Hello @jhoxiris

It is very great you share your knowledge in the field of lyrical music while you are training in this field, thank you for sharing your knowledge in Classical Music with the community!

I could only recommend that in the part where you refer to the author you can put an external link to know where you took the information about him, or otherwise it would be enough with a link that leads us to know more about the author (by the way the link you share is broken: https://www.criticadelibros.com/autores/giovanniguidiccioni), cause he focal point of this publication is your musical analysis.

Have a nice day!
