I'm looking for various informal and formal discussions/articles of
the Suzuki method of piano instruction versus traditional, especially
as it relates to young children (six and under), even though articles
discussing a "compare and contast", "plus/minus" of both methods would
be interesting.  Thanks!

I learned flute mostly by the Suzuki studio method starting at age 11.
I studied piano in more traditional methods starting at age 5. Both
are decent methods of teaching, however, the best teachers will
balance the Suzuki curriculum with traditional method books, or
vice-versa.

Suzuki is a marvel of ear training and memorization. Even as a
teenager forced into the method after I took up the flute, I saw its
potential. The younger players in my teacher's studio amazed me
sometimes.

The danger of Suzuki is that a child learns repetition and
memorization only, without the creative skills needed for technical
achievement. Example: you have probably seen a child at a piano. They
play Fur Elise, Ode to Joy or chopsticks, then play it again and
again, faster and faster. It seems they can't play much else. If
traditional method books are used as well, the child learns to adapt
technical skills and music theory to a much broader range of music.

My short analysis is: both methods have strength, but together, they
serve a young musician the best.

Good Luck!
