Psalm 150 says:
Praise the Lord with the trumpet, psaltery, harp, timbrel, stringed instruments, organs, loud cymbals and high-sounding cymbals.
We haven't used musical instruments in worship since the Temple was destroyed, as a sign of mourning. So why do we recite this psalm in the daily morning service?
Perhaps to make us look forward to the rebuilt Temple when we will be able to do these things? But these are phrased as commands, commands that we can't fulfill...
(Same with the sacrifices. Of course, these texts should be read and studied. But why must they also be in the liturgy when we can't act on them?)
