Also do you think it would be probably better to leave an open hand for flute and cello in the slurs part? I don't have much knowledge about how, for example long a flute player can hold one sound depending on the breathing capability (not familiar with both cello and flute in practical dimensions). Would it be acceptable to leave this aspect blank, without specifying anything? I wish my works to be interesting, but not impossible to play by real instruments of course.
I use MuseScore for scoring and Logic Pro X for MIDI. Unfortunately, none of the people in my music and technology class are capable of recording music either on flute or cello; I don't play those instruments at all and my piano skills are rather low as well.
Thank you for kind words! While choosing the sounds, I felt like walking on ice because of my complete lack of experience in that field. I don't think I'll bother myself with this, since I don't plan on going in that musical direction. Thanks again for the comment!
