Tramlines and Feta font caesurae

This snippet shows a way to insert available Feta font symbols as caesurae and ways to create tramlines. Normally a caesura is indicated by a pair of oblique lines lying through the top line of the staff, also called a fetura, tramlines, railroad tracks, or a cut-off. LilyPond provides several alternatives. A stylized version of tramlines is called caesura.
