  1. Accidentals, steps, scales Sharps(#) Flats(b)

  2. Look at the keyboard and notice how the sharps and flats are laid out. . A sharp is defined as the note that is one half step higher then the note you are starting on. A half step on the piano is the very next key. So, C# is the very next key to the right after the C and it happens to be a black key.

  3. Logically enough, flats are defined as the note that is one half step lower than the note you are starting on. So, Db is the next key to the left of D

  4. When an accidental has been written, all the other notes which are the same pitch, (or position on the staff), are also affected by the accidental, but only until a barline is drawn. Notes of the same letter name, but which occupy different positions on the staff, are not affected by each other’s accidentals. 3.

  5. Enharmonic tones Did you notice that C# and Db are the same key??? All notes have more than one name. The formal word for this concept is enharmonic tones. C# and Db are enharmonic tones (on the piano they sound the same, but have different names)

  6. Half steps and whole steps • The pitch of a note is how high or low it sounds. • The distance between two pitches can be measured in half steps and whole steps. • half step or semi-tone is a closest distance from one note to the next closest note higher or lower

  7. We use half steps and whole steps only in diatonic scales A diatonic scale is one that has no added sharps or flats other than what is in the key signature -- the scale's interval pattern could be played using only the white keys on the piano

  8. Using white keys only, a major scale starting on C has no sharps and no flats. Look at the keyboard and see that this scale follows the whole step / half step pattern of: root, whole step, whole step, half step, whole step, whole step, whole step, half stepC     D        E         F       G        A        B        C

  9. Now, if you will use the keyboard and make a major scale starting on D, you will find that in order to key the whole step, half step pattern, you need to add an F# and a C#. • This is how key signatures are arrived at – it really isn't just random!
