In practical terms, I distinguish between four modes or styles of analysis based on one’s priorities:
(1) as an aid for performance, which largely requires playing experience and skilled intuitions, not “readings.”
(2) as an active aid in listening, primarily knowledge of styles, music topics and conventions, repertoires, composers, and so on, along with the aural experience of melody, harmony, dynamics, texture, and tempo.
(3) as a method to identify and explain compositional mechanics or specifics (“explicate” is a technical term in literary pedagogy).
(4) as a device to provide beginning points or “windows” for “hermeneutics,” the verbally dominated work of interpretation, along with supporting details.
The last two of these are the natural focus of prolongational analysis. It is of limited, if any, value for the first two.
As was the case in the Guide to Schenkerian Analysis series (see the bottom of this post for more information), the goal here is to offer a coherent but flexible analytical, pedagogical, and interpretative tool for the musics at hand.
Nicholas Cook, in his classic but still decidedly relevant Guide to Music Analysis (1989) says the following:
There is no reason why the normal conventions of Schenkerian analysis should not be replaced by others where this has some practical advantage, provided that the analyst makes it clear what conventions he is adopting or inventing—that is to say, that he makes it clear what he sees as being prolonged and by what means. Doing this can result in useful analytical results with music which is more or less a closed book for traditional Schenkerian analysis. (Guide to Music Analysis, p. 59, emphasis added)
The value of this admonition for work with my principal repertoire is obvious (Cook himself offers a reading of a Debussy Prelude), but following directly from it is also a recognition of the role of analysis as interpretation. So long as it is hierarchical and so long as it includes background structures, prolongational analysis is never just objective in a work-out-the-algorithm sense: it is interpretive, and interpretation is never disinterested.
Elsewhere I have used an analogy to illustrate this point. Thinking of it provisionally as explicating musical design, prolongational analysis gives us a background as the “theme” of a piece,** the mechanics of “how it works,” to be sure—what is being prolonged and by what means—but also our summary of “what it is about,” how it fits with the conventions we have adopted or invented. In other words, choice of a background figure inevitably reveals the point of the analyst’s narrative, his or her “thesis,” what he or she believes about this music and wants us to believe, too. I'll have more to say about theme and thesis in a subsequent post. You can also read about it here: Themes and Lines: On Practices in Linear Analysis of Music.
** “Theme” here does not mean the main melody of a musical composition -- that would be labeled a "motif" in literary terms. Yes, it is confusing.

2018 November. Guide to Schenkerian Analysis (2018-11-14) Guide to Schenkerian Analysis
This essay is an introduction to Schenkerian analysis, one model for linear analysis/interpretation of music. This condensed version of an out-of-print manual, co-authored with Susan Tepping, provides the basis of an efficient learning experience and includes only the material from the original book necessary to that end. Two supplementary files contain appendices (File 2) and text and figures from the original book deleted from this file (File 3).

Methods for bass-line analysis that alter traditional Schenkerism are sometimes appropriate to European and European-influenced music from roughly 1890 to 1925. The examples are mainly drawn from Béla Bartók’s pedagogical collections for piano, principally For Children (1909; 1911), but also include work by Marion Bauer, Lili Boulanger, Samuel Coleridge-Taylor, and Roger Quilter, among others.
