Oh! Thank you very much. i didn't know about Acciaccatura, and at same time i took some time to read about ornaments and learned about "Appoggiatura" and "Turn" that was the other issues from the others pieces. By the way, looks much cleaner now with semiquavers on harp, and grace notes on piano. Thanks for the help.
Put a brace on the grand staff instruments. Use A minor. Harp: Split the quavers into tied semiquavers, then beam four semiquavers on each beat. Piano: Indicate tempo rubato and write in straight rhythm. Use an acciaccatura for the first E and subsequent short ornamental notes. The arpeggio should be written before the affected notes instead of after. If needed, provide a literal interpretation in one bar for clarification.
