Indeed.  Mhmm.  I would define an auxiliary, temporary function

  T = #(define-void-function (parser location name chord)
        (string? ly:music?)
        "Auxiliary function to set up tunings."
        (let ((sym (string->symbol (string-append name "-tuning"))))
         #{ \makeDefaultStringTuning #sym \stringTuning #chord #}))

that simplifies

  \makeDefaultStringTuning #'guitar-tuning \stringTuning <e, a, d g b e'>

to the much more readable

  \T "guitar" <e, a, d g b e'>

The only thing I don't know how to remove this function after it has
been used – AFAIK, Scheme doesn't allow this, but what about LilyPond?

You can break a line at whitespace as you like.
