Solutions for the Problematic 3'' Bend
The problematic 3'' means to play a draw bend of 2 half tones below the normal unbent 3 hole. Beginners do not often like this note and so to play the piece "correctly", one has to find a work-a-round. But TRY to learn how to play the 3'' properly so that it sounds right if possible. One can learn to do the bend right but know that it will take time. Perhaps try it on a higher pitched harmonica to make it easier to perform?
This may be the most vexing problem with the 10 hole blues harmonica as this note is so often needed. The following list gives some work-a-round methods that come to mind for helping this and similar problems:
1. Avoidance by either not playing it or at least playing it softly albeit a bit incorrect.
This only works if it is not an important emphasized note.
2. Play that portion an octave above so that the 3'' A note becomes the 6 draw A note.
This only works if the octave switch is done smoothly without interrupting the piece.
3. Substitute another note that is nearby and hope that no one will notice.
Often a repeat of the last note can be used effectively to do this.
4. Substitute a harmonizing note within the used scale using the problem note.
The 4 blow tonic note often works as it would here to help fix the problem.
5. Play two notes at the same time so giving the feel of the right note.
Similarly one can use a vibrato, trill or warble at that point to disguise the problem.
6. Switch to a different harp that can play that note easily for that portion of the piece.
This can only be done if able to do smoothly — which is not usually.
7. Switch positions (and harp so that the key does not change) so to have the right note.
This is a big move overall, but for some songs, it can simplify many issues.
8. Switch to a special tuned harp such as those with a Paddy Richter tuning.
Eg: The PowerBender by Brendon Powers has the 3 blow raised one full tone.
The above tips are also applicable for other problematic notes such as when the 5 hole draw is needed to be sharped. As said, it gets better with time. Sometimes you just have to say that the harp is not appropriate for some songs. Be realistic.
