Reading and playing interval changes, rather than pitch letters, is a way to approach it.
The worst thing is literally writing the letter names on the white keys, going over mnemonics like FACE
and (E)very (G)ood (B)oy (D)oes (F)ine
, and finding the labeled piano key. Even if you don't literally write on the keys (some people do!) thinking this way is a problem.
Instead of seeing...
...and then thinking middle C
is in the middle of the grand staff, every G
ood, fA
ce, F
ace.
It should be start on C
in C
major, up a fifth, up a second, down a third.
When reading the intervals from staff there are some short cuts you can develop like fifths and thirds move from line to line or space to space and fourths, sixths, and octaves alternate lines to spaces, spaces to lines.
On the motor skill side of things you should learn basic fingering positions and patterns in terms of intervals. Five finger position, scales, full octave chords, playing double notes in one hand, repeated notes, playing scales in broken intervals, etc. provide the techniques for movement around the keyboard, but they also should be understood as intervallic movements. Depending on the requirements of a particular passage you can select from that bag of technical motor skills to execute the interval changes.
In terms of five-finger position, my little passage might be executed like this...
...where (5)4
is meant to show a silent finger change to shift the five-finger position up. So, 1
is on C
and in five-finger position going up a fifth would just hit 5
, but we don't play 5
and instead replace it with 4
to shift position up, then the descending third is executed by simply putting down 5
adjacent to 4
and next hitting 3
both in normal five-finger position.
We need to start with finding C
, but after that we don't need to know anything about pitch letters to sight read the notation. We only need to know how to play fingering patterns in C
major with awareness of intervals.
Of course the particular details of a passage might require playing a particular interval, ex. a perfect fifth, in various ways. You could play this little passage using the fingering for octave chords. Here would be the basic fingering material and application of the two options...
I think this is how motor skill technique gets linked with reading notation for performance (sight reading.) The language to describe it is then not pitch letters but interval changes, and much more conveniently various relative motion types: broken chord/arpeggiation, conjunct/scalar motion, parallel thirds, etc.
If the purpose is to read staff for pitch letters, identifying chord, etc. then the proper thing to do is learn how staves are aligned to staff and then learn to recite pitch letters by thirds and fifth, ascending and descending.
It's probably hard for some people to get past FACE
and EGBDF
, because it's taught to so many at so young an age, but the various common clefs - G
, F
, and C
are aligned by the "swirl", "double dot", and "little c" on to line so those lines are identified respectively as G
, F
, and C
. From those reference points you can move up/down by thirds or fifths (an extensions by single steps) to identify the rest of the lines and spaces. ACEGBDFAFDBGECA
and AEBFCGDADGCFBEA
should be automatic patterns.
I'm not a music teacher. I'm self taught for most everything in music. But what I've written summarizes my reading from a lot of teaching material.
