Final answer:
Hymnody refers to the practice of singing hymns in a religious context, while psalmody specifically refers to the singing or chanting of psalms. The main difference lies in the texts being sung - hymns are usually composed by individuals or groups, while psalms are biblical texts.
Step-by-step explanation:
Hymnody refers to the practice of singing hymns in a religious context. These hymns are often written in a formal, poetic style and are typically sung by a congregation. They can be accompanied by musical instruments or sung a cappella.
Psalmody, on the other hand, specifically refers to the singing or chanting of psalms, which are religious texts found in the Book of Psalms in the Bible. Psalmody may also involve a congregation singing together, often with a leader or choir leading the melodies.
While both hymnody and psalmody involve singing in a religious context, the main difference lies in the texts being sung - hymns are usually composed by individuals or groups in the congregation, while psalms are biblical texts.
