Making cross-staff beams look better

Cross-staff beams might be very steep, which can be ugly sometimes. This snippet demonstrates how to change that.

\version "2.24"

\score {
  \new PianoStaff <<
   \new Staff = "RH" { \clef treble \time 3/4 s2.*2 }
   \new Staff = "LH" { \clef bass   \time 3/4 s2.*2 }
   \context Staff = LH
    \relative c' {
     \stemDown
     c,8 [ g'
       \change Staff = RH
       d' a' e' b' ] |
     \override Beam.concaveness = #1
     b [ e, a, d,
       \change Staff = LH
       g, c, ] |
   }
  >>
}
