Here is another beautiful classical music sheet named Come, Holy Ghost, our souls inspire(Veni Creator Spiritus). You can found the download link below to teach your choir.
Come, Holy Ghost, our souls inspire, and lighten with celestial fire. Thou the anointing Spirit art, who dost thy sevenfold gifts impart. Thy blessed unction from above is comfort, life, and fire of love.
Enable with perpetual light the dullness of our blinded sight. Anoint and cheer our soiled face with the abundance of thy grace. Keep far from foes, give peace at home: where thou art guide, no ill can come.
Teach us to know the Father, Son, and thee, of both, to be but One, that through the ages all along, this may be our endless song: Praise to thy eternal merit, Father, Son, and Holy Spirit.
