Turn left into Schofield Barracks McNair Gate. After passing the sentry, make an immediate right onto Ayres Avenue. Hale Kula Elementary School is on the left. *If you do not have a military base pass, you will need to enter through Lyman Gate (see map).
There are 12 possible keys any particular song can be played in. This is because of the 12 notes on the piano keyboard, A, A#/Bb, B, C, C#/Db, D, D#/Eb, E, F, F#/Gb, G, and G#/Ab. A song can be played so that any one of these twelve notes will be the tonal center or home base.
Now we know that C is different from G when we hear it and play it. The musical alphabet only uses seven letters: A, B, C, D, E, F, and G. Once the note G is played, the very next pitch is called A restarting the musical alphabet all over again. The entire musical alphabet can be cycled through many different times in a single piece of music. When you look at the white keys on the piano, you will see a repeating pattern of the seven letters used in music.
