stemless note

[Mark Stephen Mrotek]

Hello:

 

In the attached snip, the first beat of the second measure has a “f4.” without a stem.

 

The error messages suggests using polyphonic voices. Since I am using << \\ >>, I do not know what that means.

 

I have tried changing stem direction - \stemUp, \stemDown.

I have tried shifting the note - \once \override NoteColumn #'force-hshift = #xx.

 

Neither worked. What should I do now?

 

Thank you.

 

Mark
