Why do intervals matter in worship?
Intervals are the building blocks of harmony and melody. Understanding them helps you write backing vocal parts, voice chords on keys, and make decisions about which notes work together. The major 3rd and perfect 5th are the most consonant intervals and form the core of every major and minor chord in worship music.
What is the most common harmony interval in worship?
The major or minor 3rd above the melody is the most common harmony in contemporary worship. It blends smoothly with the lead vocal and stays within the key. The perfect 4th below the melody is the same note as the 5th above the root — it creates a full, choir-like sound and is widely used in three-part worship harmony arrangements.
What is interval inversion?
When you flip an interval — move the bottom note up an octave or the top note down an octave — you get its inversion. A major 3rd inverts to a minor 6th. A perfect 5th inverts to a perfect 4th. The rule: the two numbers always add up to 9, and major inverts to minor (and vice versa), while perfect stays perfect.
