I'm talking about leaving out some notes in a musical composition. The question is which notes can be ommited? Keep in mind that out of all the voices in a piece, the top note and the bottom note are the crucial ones, because the top note (soprano voice) often is the bearer of the most developed melody and the bass - foundation of harmony.
Therefore occasionally we can leave out some of the middle notes. Of course, in organ music, there are many places where the melody is in the middle voice or where there is more than one melody present at the same time. In such case, you can ommit only the voice which doesn't have melodic interest.
Therefore, this trick only works for thick chordal texture. If you see polyphony on the page, every single voice is very important. Each voice is like a character, a person. If you forcefully silence one person in a discussion between the 4 people, he or she will be quite disappointed.
But if you take a large-scale piece by Max Reger, for example, a lot of times in fortissimo places you will find chords of 4-5 notes in each hand (and even the double pedal). This is a very difficult music to play for anybody, not only for a person with small hands. So you can easily reduce the texture somewhat by leaving out one note which is least important in each hand.
This trick sometimes works for hymn playing as well. But you have to be careful by using it. Avoid the temptation to apply it in any situation where you seemingly have trouble reaching for wider intervals. Instead think hard about the possibilities of the most efficient fingering has to offer.
