A tip to remember when playing acoustic notes is to avoid keeping the fingers flat. The fingers need to be squared, with the joints making a box shape to produce a clearer and more melodic sound.
In addition to keeping the fingers square and firm on the strings, players should also avoid putting their fingers too far away from the frets. Different chords have different finger placement arrangements, and sometimes pressing down too hard can have an undesirable effect. Players should keep the rough sections of their fingers pressed on the strings with a controlled and precise amount of pressure to get the desired results.
