How to align text vertically and change font document-wise

[Ivanov Dmitry]

Here is the minimal working example:

\relative c'' {
  \clef violin
  \time 3/4
  c,2_"C" e8_"E" c'_"C"
  g'2.
  f4 e d
  c4 c, r
}

Is it possible to vertically align all the characters by the bottom
line? How can I change the font for text document-wise, for example
change the size and make it bold for all the markup texts?
