THIS IS FOR THE TOTAL BEGINNER

Here is a quick start for those who want to begin to understand the piano.

Here is PART 1

Here is the continuation (part 2)

The terms you need to remember are:
KEYS = the mechanisms you press on the piano/keyboard to produce sound
KEYS also = the tonality of the musical piece.  The resting place, The Key you are playing in.
HALF STEP = the distance between one note and the very next note on the keyboard
WHOLE STEP = the distance between one note and the note two keys over from it. (2 half steps
INTERVALS =  The distance between one note and another.
UNISON =  The smallest interval. One note and that very same note.
OCTAVE = The distance between a note and the next occurrence of that note going either up or down the keyboard.
FORMULA FOR BUILDING A MAJOR SCALE
W-W-H-W-W-W-H
*w = whole step, h = half step

I hope this helps a bit.  You'll need a keyboard to practice on.
GLAD YOU'RE GETTING STARTED!
