One of the methods that tackle the challenge of teaching very young children is the Suzuki method. The idea of the method is that playing an instrument goes first, reading later. Similar to the way children acquire their language: they learn to speak fluently first and the reading comes later. The parents often ask: "When are they going to read music?"
It is common knowledge that traditional notation is a bit abstract for most young beginners. Not surprisingly, many of the traditional method books use various simplified note systems at the beginning. This helpful approach underpins the Utopia system as well. That allows the young beginners not only to play the music they enjoy and to develop their piano technique, but also to acquire pre-reading skills early in their studies. The benefits of the traditional and Suzuki method thus become synergetic and amplify each other.
