Hello all, I write mostly arrangements where I bring a melody voice down to the double bass (my instrument :-))
Double bass is written an octave higher then sounding, so a lot of times, the score lookes OK, but in fact there are voice crossings between lefthand of piano and the double bass (what gives unwanted/unpleasant voice crossings. To check this, I transpose the double bass voice down an octave and manually check the boths voices. Wonder if there is a function in lilypond to do this fastly. Like the coloured noteheads when checking a voice against the ambitus of an instrument. Regards, Eef
