Read the 7 daily Psalms on Sefaria for the surrounding biblical/liturgical context.
The Mishnah, tractate Tamid chapter 7, describes the daily service in the Second Temple in detail. After the morning tamid (continual offering), the Levites, the temple choristers, would ascend the platform and sing the day's psalm with full musical accompaniment. The Mishnah names each psalm and explains why each one fits its day, mostly by linking to that day of the creation week (Sunday = day 1 of creation, etc.). After the Temple was destroyed in 70 CE, the rabbis preserved the seven-psalm rotation as part of the post-Temple synagogue liturgy.
The Mishnah's explanations connect each psalm to a day of creation:
The Temple service was musical. There were ~12 Levites singing on a daily basis (more on festivals), accompanied by musical instruments, the harp (kinor), lyre (nevel), cymbals (tziltzelim), trumpets (chatzotzrot). The Levites stood on a wooden platform (duchan) overlooking the courtyard where the sacrifices were offered. After each day's morning sacrifice, the Levites would sing the day's psalm. Crowds would respond. The performance lasted ~10-15 minutes.
After the Temple's destruction, this musical tradition mostly fell silent, the Sages forbade instrumental music in synagogues as a sign of mourning for the Temple. The psalms remained, but the orchestra was gone. Today, in synagogues across the world, the seven psalms are spoken or chanted simply, without instrumental accompaniment, every morning, the verbal trace of a vanished orchestral liturgy.
