when displayed in other keys.
I wouldnt do arpeggios with this fingering!For any arpeggio in any inversion starting on a white key, use thumb in R and 5th in L.For arpeggios starting on a black key, the RH thumb comes on the first white key going up. The LH thumb comes on the first white key going down.If there are no white keys, use thumb and 5th.
I understand what you say, but it is better to have flexibility in hand shapes to account for arpeggios as they occur in actual pieces.Anyway, out of interest, did you get the point of teaching scales by the two wholetone scale method instead of the key signature method?
Its not circumventing key signatures, its discovering them!This way a young student could easily work out the notes for any major scale, by taking 3 notes from one WT scale then 4 from the other. So for A major (for example) what did you get? What then is the key signature? So where will we place A on the key clock ... etc.In any major scale, doh ray me is from one WT scale and fah soh lah te is from the other. It also explains why the fah and te are important notes. (Fah = 4th degree, Te = 7th degree in relative solfa.) Fah being the last flat and te the last sharp. To change the scale to the next nearest related, either end of (fah soh lah te) has to be changed to belong to the other WT scale, either fah raised or te lowered leaving either (soh la te) or (fah soh lah) as the 3-some of the new scale. Thus the related keys are soh and fah.I think this WT scale method is easier to explain than the tetrachord method where you have to construct 4 notes by TTS twice. Just because things are usually done this way does not mean it is necessarily the best way to explain something. I am all for expanding understanding and seeing things in new ways.Like the symmetry of ABCDEFG ...
Well the WT scales can be taught without the key colour being changed. One WT scale is the 3 back keys plus 3 white (CDE). The other is the 2 black keys plus 4 white (FGAB). So you test them in playing the 3-3 wholetone scale and the 2-4 wholetone scale. You point out what we mean by wholetones, specially showing where they cross from black to white. You also point out what we mean by semitones. Point out that if you move by a semitone, you get into the other WT scale. For kids who have a logical, mathematical or scientific type of brain, this would appeal. For kids without (aaggghhh), you just teach the mnemonics without trying to explain anything!I always wanted explanations when I was young, and was never satisfied with the conventional answers. Why is treble clef different to bass clef? The fact is, it was a quirky error of judgement somewhere in history! There is no logical reason why they could not have gone with the French violin clef that had the G on the bottom line.When I first saw that ABCDEFG made a symmetrical pattern, i thought "So thats why the notes are named the way they are!" If we were meant to start with C, it would have been called A!I dont teach kids to pass theory exams any more. I try to teach them piano skills, one of which is playing sheet music, classical style. But too often, the kids aim is to do other things and I try to keep a balance. Sometimes we play melody by solfa and "Home" (tonic) and "Away" (dominant 7th) chords, or we interpret chord symbols and make our own arrangements or versions of pieces. Also kids want help with how to pick up pop songs by ear, or how do some improvising in boogie blues style etc ...Playing classical music is not what most would people want to do, unless it was a bit easier. Anyway thats my outlook ...
