The "nephesh" is very interesting. It accounts for the formulation of "...He breathed life into [Adam and Eve]" as well as the occasional description of the Holy Spirit as 'breath.'
Ratzinger uses the "breath" or "pneumos" concept in affirming that the human voice (operative only with breath) is the principal and most sublime way in which we worship God, (affirmed countless times by David) and then applies that "breath" concept in a sidebar-fashion to remind us why the pipe organ is specifically preferred as the instrument for Catholic Churches.
The author's quick dismissal of "life"/"death" OT references--not connecting them to the Hebrew concept of "life," as in the "life eternal" phrase used by Xt to the Samaritan well-woman is unfortunate, because his conclusion is false as a result.
