Same Foot before Changing Direction
On passages in quarter, eighth, and sixteenth notes sometimes we use same foot instead of alternate toes technique. Here applies the general rule: use same foot before changing direction. This means that in a passage like C D E D we play with the same foot notes D and E because after ascending notes D and E the melody changes direction downwards. So the entire passage, such as C D E D E F G F G A B G would be played left, right, right, left, left, right, right, left, left, right, right, left, and left.
Same Foot on Long Note Values in Extreme Edges of the Pedal Board
In Baroque and Renaissance organ music, chorale-based compositions often employ cantus firmus technique – placement of the chorale melody in long note values (half and whole notes). Cantus firmus method can be used in any voice. Instances of cantus firmus in the bass were especially common because they could be played on a separate pedal division with a different sound color. Moreover, if cantus firmus was used in any other voice, it could still often be played with the pedals. The normal way of pedaling such melodies was alternate toes technique. However, in extreme edges of the pedal board one could play long notes with one foot because the traditional alternate toes technique is uncomfortable.
I recommend that you write in pedaling in every piece you play on the organ, at least in the beginning. This will prevent you from making accidental pedaling choices which will not necessarily be correct and efficient. With experience, however, you will start to notice familiar patterns in pedal lines of your organ music and gradually your pedaling choices will become automatic and natural. In other words, if you practice writing in the correct pedaling regularly, with time your pedaling will become instinctive and you will not need to write in any of it.
