Pitch  The highness or lowness of sound.
Octave  From one letter up or down to its next occurrence.
Octave Register  The space from any C up to the next B.
Staff  Indicates the precise pitch desired. An arrangement of five lines and four spaces that can be extended through the use of ledger lines.
Ledger Lines  Used to extend the staff.
Clef  Must appear at the beginning of the staff in order to indicate which pitches are to be associated with which lines and spaces.
Grand Staff  A combination of two staves joined by a brace, with the top and bottom staves using treble and bass clefs, respectively.
Major Scale  A specific pattern of small steps (called half steps) and larger ones (called whole steps) encompassing an octave.
Half Step  The distance from a key on the piano to the very next key, white or black.
Whole Step  Skips the very next key on the piano keyboard and goes instead to the following one.
Tetrachord  A four-note scalar pattern.
Accidental  A symbol that raises or lowers a pitch by a half or whole step.
Key  Identifies the first degree of a scale.
Key of G Major  Refers to the major scale that begins on G.
Key Signature  A pattern of sharps or flats that appears at the beginning of a staff and indicates that certain notes are to consistently raised or lowered.
Enharmonic  Notes that are spelled differently but sound the same.
Transpose  To write or play music in some key other than the original.
Circle of Fifths  A diagram like the face of a clock that aids in the memorization of key signatures.
Natural Minor Scale  A minor scale formation, similar to a major scale with lowered 3, 6 and 7.
Harmonic Minor Scale  A minor scale type which can be thought of as a major with lowered 3 and 6.
Melodic Minor Scale  A minor scale type which has an ascending form and a descending form. It lowers scale degree 3 when ascending and scale degrees 3, 6, and 7 when descending.
Relatives  Major and minor keys that share the same key signature.
Parallels  Major and minor keys that share the same starting note.
Interval  The measurement of the distance in pitch between two notes.
Harmonic Interval  Separates pitches that are sounded simultaneously.
Melodic Interval  Separates pitches that are sounded in succession.
Unison  In discussing intervals, the term used instead of 1.
Octave  In discussing intervals, the term used instead of 8.
Simple Intervals  Intervals smaller than an 8ve.
Compound Intervals  Intervals larger than and including 8ve.
Perfect  A modifier used only in connection with unisons, 4ths, 5ths, 8ves, and their compounds (11ths, and so on).
Augmented  When a perfect or a major interval is made a half step larger without changing the numerical name.
Diminished  When a perfect or minor interval is made a half step smaller without changing its numerical name.
Tritone  The term used for the +4 or its enharmonic equivalent, the (5.
Interval Inversion  When one puts the lower note above the upper one (or the reverse).
