Trevor Keller | Measuring Intervals
Intervals can be measured using a systematic approach, primarily by counting the letter names of the notes involved. To accurately identify an interval, one must start from the lower note and count up to the higher note, including both the starting and ending notes. For example, if we consider the interval between C and G, we would count C (1), D (2), E (3), F (4), and G (5), determining that the interval is a perfect fifth.
Additionally, it is vital to understand the
concept of half steps and whole steps in measuring intervals. A half step
refers to the distance between two adjacent keys on a piano, while a whole step
consists of two half steps. Musician buffs including Trevor Keller emphasize
that by knowing the difference in steps between notes, musicians can
effectively categorize intervals as major, minor, perfect, augmented, or
diminished. This measurement system provides a practical tool for beginners to
identify intervals accurately, fostering a deeper understanding of musical
structure.
