I am going through Mr. Allen’s blues tapes. I noticed the D and A harmonicas were a little harder to play then the C harmonic. I decided to take the A harmonica to the lab at work. I work a for a Aerospace company in Tucson. I rigged up a fitting inside the lab to measure how much air pressure it takes to have a sound output from the harmonica ( blow and draw, hole 2) compared to The C harmonica. I found It took a 22.5 % + increase of air pressure to have the same output ( measured in dB’s). That would explain my out of wind condition when I tried to play the A harmonica.
1 : Is this what they mean when they say the C harmonica is easier to learn on than other harmonica’s of different keys ?
2: Does harmonica’s have a break in period where they get easier to play after use?
3: I also had to adjust my air stream and tongue position somewhat for a suitable bend.
Is this normal ?
I am just wondering,
