Tina appears to be remarkably talented. Here she is doing everything that Eddie van Halen is famous for:
Which brings some interesting thoughts: this kind of guitar playing is usually associated with teenage (and later) males showing off their musical virility. When a 14 year old girl does it, it kind of calls all those theories into question. Remember that the "Red Priest", Antonio Vivaldi, taught for thirty years at the Ospedale della Pietà, an orphanage. Most of Vivaldi's music was written for the orchestra and choir there which was composed of girls as the boys had to leave the institution at age 15, while the girls could remain. Apart from many cantatas and other sacred vocal music, Vivaldi wrote some 500 concertos for his ensemble at the Ospedale! They were famous throughout Europe for their virtuosity and musicality--all under the training of Vivaldi.
Here is a setting of the Gloria by Vivaldi with choir and played on original instruments which might give a bit of an idea of what those kids at the Ospedale might have sounded like:
Here is a fine violin concerto in D minor by Vivaldi, to give a bit more perspective:
The thing about Vivaldi, and Haydn and Mozart for that matter, is that he composed music with an ease and facility that few could match. He composed music the way the rest of us walk down the street or breathe! Five hundred concertos! Just think about that for a moment.
Until Beethoven came along and problematized composition at the same time he revolutionized it, a composer could simply write music. But Beethoven did something: he opened up depths that later composers found it difficult to ignore and so composition became something fraught, something difficult, a struggle.
But not for Vivaldi. And we should not make the mistake of assuming that because Vivaldi composed with ease and grace that the music is facile and trivial. Plainly it is not. Vivaldi demonstrates sprezzatura in composition. Something I wrote about in this post.
