Let me just come out and say that I don't care for any one method. I believe that anytime you decide to teach with one technique you limit your effectiveness with the vast range of students you will encounter in a classroom. I feel that every method has brilliant ideas and tools that one can employ, but keep in mind that it is only one school of thought and as the saying goes "two heads are better than one."
Before I begin I think we should recap the major methods, which I honestly have not looked at since my undergrad years in college. The three main ones I am talking about are the Dalcroze, Koldaly, and Orff methods. So please allow me to give an over simplified overview of these three methods.
The first method is the Dalcroze method. The main part to this "method" is about using physical movement to understand rhythms, which is why it is also called eurhythmics. The mentality of using movement is that it has students "feel" the music, which in turn helps internalize the beat and rhythms. This method also uses solfege, with moveable "do." This meaning that the sight singer would use the tonic as "do" rather than the fixed "do." The last element of this method is improvisation. This is the art of creating music "on the spot."
I feel that implementing these techniques would really benefit anyone who teaches younger students due to the fact that it resembles play. Moving, experimenting, improvising and singing is a strength of an elementary aged student. I would wish I could see more of this in the high levels of education, but by the time students are in middle school or high school they have already been infected with self consciousness and insecurity topped with a fear of being "wrong." The end result being that it is harder to get them to express themselves with movement, but if you can then do it!
The second method is the Kodaly method. This method seems to be more of a visual method that uses hand signs, pictures and notational symbols for students to use, thus providing a visual representation of sound. There is also an emphasis of using folk tunes and a stress to use of pentatonic scale to help students make a close connection to the music. This method also stresses the use of moveable "do" solfege and singing. The recorder and xylophone are also tools attributed to the Kodaly method.
The Kodaly method seems to be sensible for the visual learner since there are many visual cues to help translate sound. With the use of simple and natural instruments such as the voice, recorder and xylophone one begins to see the affordability of this method. Also, by using instruments that come naturally to the learner students can move beyond the basics faster and begin creating music and making musical decisions. Due to these reasons I can see why this method is employed.
The Orff method is the final method I wish to discuss. This method also stresses the need for movement. We see the simple realization resurface that using the natural instrument of the body helps the students internalize and translate music. We also see the use of body as a percussion instrument, improvisation, and the pentatonic scale in this method. This method also implements solfege, which makes it seem rather similar to previous methods. The only major difference I can detect with this method is that there is a stress to work with different timbres, which is why this method uses the glockenspeil, xylophone and metallophone.
I think this method is more of a blending of previous methods, which makes it very versatile and would relate to a larger range of learning styles.
Now that we are all familiarized/re-acquainted with these methods allow me to summarize my feelings on this whole method mania madness. I cannot stress enough that focusing on one method is like focusing on one student. The best way to impact the largest numbers of students is to adapt and evolve, so without any further ado let me introduce you to the my theory of method evolution. I call it, the Buckley Theory of Method Evolution or B.T.M.E for short. Feel free to spread this theory of evolution with everyone you know. Anyway, my philosophy is that by taking the best of every theory and continually changing to incorporate new tools of emerging theories will be the best for the students. The best of each methods to me are as follows:
1. Movement is a must! We train kids out of movement and I hate this. Our body is the strongest tool we have and to make it sit like a stagnent pool will only produce the same foul smelling stenches of a bog or swamp. If movement is so wrong and corrupt in a classroom then why are we all taken away with the beauty of a professional dancer?
2. Solfege and sing! The voice is a great instrument and one we have been using since we took our first breath. Sure, some students are tone deaf and have problems matching pitch, but they will not improve unless we allow them to make noise with it first. If you are really worried and they are self conscious there are still fantastic beat boxers for them to learn from. Solfege is a great tool and should be used in chorus and if possible the general music classroom. Stop pounding out notes or showing off your amazing piano skills and allow the students to think for themselves.
3. Let the eyes see what the ears experience. Some students may not need a visual representation of the sound, but there is no denying that visual aids help and the more learning styles students use the better chance of long term retention. I don't care if you use pictures, notation, MIDI data, or sound waves. Sound is fantastic, but the eyes ca be involved as well. Its hard enough as an adult to just use one sense so imagine being a sugar addicted child asked to sit and listen. It usually ends badly.
4. Pentatonic is universal so use it. I watched this amazing video with Bobby McFerrin at a science convention prove that the pentatonic scale is already internalized and universal. (Watch to see what I mean: http://www.youtube.com/watch?v=ne6tB2KiZuk ) There have also been countless studies that every known culture bases their music using the pentatonic scale. Use what comes naturally and the students will go far.
5. Instruments are tools but timbres are important. I don't care what instrument they use, but there should be an array of them so students can distinguish and describe various timbre changes.
In closing, allow the students to learn with their strengths and don't be afraid to think outside the box. The only wrong thing is limiting yourself and your students.
