2 in A minor, "Molto vivace", is the second of twelve Transcendental Études by Franz Liszt.
This piece is an extremely volatile one as fierce alternating notes in fortissimo fire away.
Soon the notes alternate even more fiercely, followed by a flying right hand arpeggio accompanied by long arpeggiated chords.
As the climax of the piece approaches it crescendos and plays even fiercer low pitched notes, and soon the right hand figures explode with erratic chords that climb high up to the keyboard and then back down.
The climax then ensues as both hands alternate on the same notes that climb 5 octaves up the keyboard and down again, then fires up again and down again.
