"Alza-púa(?)" technique for i-m-a fingers or combination

Hi, Tonebase staff and community!! 

i wanted to share for a while now a technique that I developed -though i'm not claiming fatherhood to this idea, as it seems to have surficed in many ways in different places at more or less the same time- with Luigi Biscaldi (Angelo Gilardino's assistent teacher) when i was studying under Angelo in the 2000s. 

Though it's not exactly the same movement as the alza-púa (as the wrist is not involved) the technique is built to resolve repeted pair or trios of notes in chord form with i-m and a fingers. 

This plectrum-like  way of performing repeated chords allows for a very relaxed legato, distinct and rapid attack over repeated chords and can be combined also with thumb's alza-púa to perform 4 note repeated chords. 

In my carreer, I have used this over a wild amount of different musical works with splendid results and i'll be happy to share more about it if any of you are interested. I leave you some links for you to hear the results of this technique:

I have used it also in music by Sor (repeated thirds), Villa-Lobos (rythmical acompaingnement), Turina, Brouwer, Mertz, Legnani, Gilardino, pick your choose...

I find it strange that this technique is not yet teached all over at conservatories as part of the sylllabus as much as the thumb use as capotasto as shown by Gian Marco Ciampa in one of Tonebase's videos. I hope that this post will arise your interest in this technique!!
