Which traditional music composer used five finger patterns extensively in piano compositions?

But first, why is learning and playing five finger patterns (5F's) so valuable?

• By doing so, you also learn all the triads in their root positions.
  
• After learning all the root positions of triads, you're ready to build inversions of them.
  
• Five finger patterns are important warmups for keyboardists who are interested in pop and jazz.
  
• 5F's are very useful at the early intermediate level, along with triad inversions, in reading lead sheets with chords.
  
• Five finger patterns are equally important for keyboardists who are interested in traditional piano repertoire.
  
• They are the first five notes of a scale.
  
• The warmup pattern is a good mid to late intermediate level finger exercise.
