[MEI-L] Measure 2 of Erlkonig

[Cundiff, Morgan]

I am working through the MEI-1st tutorial and checking my results by rendering in Verovio. Several of the given solutions in the tutorial do not render properly but there is one spot in particular I would like some help with.

Can someone show me how to MEI-encode the second bar of The Erl King as found on bottom of this page (No. 8 Complete Measure) such that it will render correctly in Verovio?

I am having trouble making the <bTrem>'s  properly align (in time) with the notes in the staff below.

Thanks,
Morgan
