We know that private lessons had been available for at least two centuries or more, but now in 1821 at a Madrid bookstore named Gobeo or Goveo as well, group lessons in reading guitar music became available. Of course the sales of the sheet much would add to the economy of this location as well.
100 years later in Buenos Aires, the Testuri sisters, Victoria and Magdalena, who were both child prodigies with their photos and articles in magazines when they were very young, some 20 years later they offered guitar lessons and student recitals in a college environment, being some of the first professors of guitar in the higher education level of stature, as documented in my book:

Lessons were available from 7:30-9:30PM

It is open from half past seven at night until half past nine. It is subscribed at a rate of 40 reales, per month when the Gobeo bookstore in front of the national printing press building."
