Melodies and meter are two fundamental aspects of music that work together to create a cohesive and engaging experience. The melody refers to the tune/musical arrangement of notes. Meter refers to the rhythmic organisation of music. It provides a framework for the melody. To illustrate the relationship between them, consider the well known hymn ‘Amazing Grace.’ Amazing Grace is composed in Common Meter (8.6.8.6.) and often sung on the melody ‘NEW BRITAIN.’ It can also be sung using other melodies, so long as they are also in Common Metre (8.6.8.6.). For example, ‘AZMON’ can also work as a melody to use when singing ‘Amazing Grace.’
If the recommended melody for a particular song is unknown/difficult, you can choose another melody which is on the same meter. It is important to choose a melody that matches the words of the song. For example, if the song is a lament (Psalm 42), then a melody which is slower and contemplative is more appropriate than a melody which is fast and exuberant.
