There are all kinds of meanings traditionally associated with the shofar blowing, as well as with each of its individual sounds. During the Rosh Hashana service, we have many sets of repetitions of the different sounds, associated with different parts of the service. It seems that it ought to therefore be possible to assign specific things to think about to each individual shofar call, based on which sound it is and where it is in the service and in its set of calls. That way, a person could be sure to cover all of the different meanings of the sounds and properly complement that awareness with awareness of the adjacent service.
Has anyone ever written a list of such assignments, so that I could look at it at each part of the service and have a good idea of what to think about right then? If not, are there general principles listed anywhere that we could use to generate such a list?
