How To Practice Use the major scale to practice your dropoffs - A great drill for practicing dropoffs is to go through each note of the major scale using the dropoff technique. If you are successful with this, try to throw some dropoffs into any songs or riffs you know from memory. Be sure to listen to the example in the above 'dropoffs' sound file. Warbles General Information Warbles are very common in blues playing - A warble is done by rapidly moving back and forth between two adjacent notes. It is typically done between holes 4 and 5 draw or 3 and 4 draw.
Warbles are one of the most common techniques found in blues harmonica playing.
This is just the opposite of slides, dropoffs, and the standard technique of going from hole to another hole. Actually a warble is done with two different techniques depending upon how fast you want the warble sound to be. This is a smaller, faster, more condensed motion then the previous one. Try to keep the volume the same on the warbled notes as if you were just playing a strong clean single note. We have a tendency to forget about about the breathing when we are focused on another technique.
