A power point presentation, a recording of ,² Carnival of the Animals², by Saint Saens. Worksheets : building tetrachords and major scales,
Play a recording of Saint-Saens¹ of Pianists , from the ³ Carnival of the Animals² , as students walk into the classroom. Ask them if they hear any repetitions? Can they visualize a story? What does the music remind them of?
As the discussion touches upon hearing of a pattern going up and down I will introduce the new subject, tetrachords and major scales by using my Power Point presentation.
After the presentation, I will address a few questions to the class so as to review the terms used in the Power Point presentation :
A brief review of the prior knowledge:
What is a half and a whole step?
Ask the students to go to the keyboard and instruct them to find and play half and whole steps.
What is a sharp; a flat ?
Where do you need to go on the keyboards to find a sharp; a flat ?
Have students find them on the keyboard.
Then the students will be asked to complete worksheets on tetrachords using the keyboard. After they complete the tetrachords , at the keyboards, ask them to pair into groups of two and work on building scales from their tetatrachords . After they are done building at least two scales, have them go to the computers and instruct them to login and select Music Ace I. As they complete the review and the game part of the major scale lesson,( of the Music Ace program), they will be asked to go back to their keyboards. There , using the keyboard, they would be asked to build and write down on a sheet music two major scales.
