Hanon's exercises entitled "The Virtuoso Pianist" are going well so far.
The first part (which I'm on) consists of 20 exercises to increase finger agility and strength (especially in the naturally weak fourth and fifth fingers).
The second part consists of 23 exercises that further prepare the fingers for the third part which consists of what are called the "Virtuoso Exercises".
The first 20 exercises are to be played starting at 60bpm and working up to 108bpm. Here's how I'm doing them.
with the tempo of one pair of exercises being the tempo I played the previous pair the day before.
The sequence of tempos I (plan to) progress through is: 60bpm, 70bpm, 80bpm, 85bpm, 90bpm, 95bpm, 100bpm, 105bpm, 108bpm
I'm currently at 95bpm on 1 & 2 down to 60bpm for 11 & 12.
