Aligning and centering instrument names
The horizontal alignment of instrument names is tweaked by changing the
Staff.InstrumentName.self-alignment-X property. The
\layout variables indent and short-indent define
the space in which the instrument names are aligned before the first
and the following systems, respectively.
\paper { left-margin = 3\cm }
\score {
  \new StaffGroup <<
    \new Staff \with {
      \override InstrumentName.self-alignment-X = #LEFT
      instrumentName = \markup \left-column {
        "Left aligned"
        "instrument name"
        }
        shortInstrumentName = "Left"
      }
      {  c''1 \break c''1 }
    \new Staff \with {
      \override InstrumentName.self-alignment-X = #CENTER
      instrumentName = \markup \center-column {
        Centered
        "instrument name"
        }
      shortInstrumentName = "Centered"
    }
    { g'1 g'1}
    \new Staff \with {
      \override InstrumentName.self-alignment-X = #RIGHT
      instrumentName = \markup \right-column {
        "Right aligned"
        "instrument name"
      }
      shortInstrumentName = "Right"
    }
    { e'1 e'1 }

  \layout {
    ragged-right = ##t
    indent = 4\cm
    short-indent = 2\cm
  }
}
