Approaching the last line of the page. Big long trill on the C for 8 bars. Here we go. One two, two two, OK turn now. Three two, four t. Come on, turn. Five two, TURN THE PAGE. Turn to look at desk partner. Seven two. AARGH. Too late ! It gets complicated on the new page with mixed bars of 2 and 3. One two, one two three, one two three, one two, one two , one two three. Is this bar a two or a three one, and precisely which one is it ? It’s nearly half a page before I find the way back in. Note to self. Write TURN HERE six bars earlier and in bigger letters.
sounds like you need a clap-nav. a device which say ‘page turn ahead, you are approaching page turn in 3 bars, turn left here’,
