I'm having a heck of a time wrapping my head around appoggiatura and acciaccatura and other grace note notations to achieve the performance I'm specifically looking for.
The image above represents how I'd like this chord performed (but it's ugly AF). In short the grace note should be crushed ON the beat and quickly resolve to the fifth. This is why I selected the acciaccatura as my symbol as shown in the score below:
Based on everything I've read recently (to my shame, I should know this stuff) this isn't quite right, but neither is the appoggiatura either. This is further confirmed by how MuseScore performs the second version (plays the grace note ON the beat but also delays the bottom note to strike at the same time as the resolved fifth).
Is my notation (with the additional text) okay or is there a more clear / more accurate notation I should use to better convey my intention, short of explicitly writing that really ugly but accurate notation in the first example (this is for a kids/beginner piece so should try not to look too intimidating, but still be correct)?
