Basic Elements Unit #1: Major ScalesThe first element of theory we've got to learn is the intervallic shape of the major scale. Our goal for this lesson is to be able to carefully build it up, step-by-step, following the "WWHWWWH" pattern. Don't worry, Printout #1: Major Scales explains it all.
Extra Practice for PC or MacI strongly recommend that you check out emusictheory.com, which offers a bunch of free quizzers that will work in any java-enabled browser. Here's the app for scales on treble clef and bass clef. You'll have to tweak the settings at first - make sure you scroll down and turn off everything but major scales!
Also, if you have a Windows PC you could try my rudiments quizzer which will drill your scales etc. in a text-based format.
Extra Practice for iPhone/iPadMusicopolous ($5) is a nice app that packs in tutorials and quizzes on a whole range of theory topics, including your major scales.
