As most of you know, I am a fan of tenor tuned chromatics. How I became a fan is really, perhaps, more a matter of luck and expediency than anything else, but I am a fan just the same. I have always enjoyed the lower end of the chromatic. Growing up I played a lot of clarinet and saxophone and I used a CBH 2016 which covered, basically, the full range of either and allowed me to share music between my various instruments. As I got older, focused more on harmonica, and focused more on jazz I found myself looking for a harp that was designed specifically for my needs. Part of that need was to find a 12 or 14 hole instrument I could cup more easily and amplify more effectively. So, I took a look at my 64 chromatics and discovered that, since I was playing a lot of saxophone lines, I didn’t have very much wear in the upper octave ;-). I quickly realized that for my specific jazz interests I could move to a tenor tuned instrument! So, I started exploring tenor chromatics and found out a few interesting things.
First, tenor reeds have a relatively "short" size for the pitch they produce. Tenor reeds do fit well on a standard size instrument and they are longer than standard tuned reeds by a slight bit, but they are noticeably shorter than the same pitched reeds on a 64. So, for the pitch they are producing they are relatively small. This is most noticeable on the top end where mid range pitches are given very small reeds. There are advantages and disadvantages to this set-up. On the lower end of the tenor, the reeds are just big enough to control well, but not as large as 64's and result in, generally, more responsive playing. Response is usually a function of gapping, but, after a while playing well gapped instruments you begin to notice that these reeds take less energy to "get moving" and don’t shake, rattle, or honk as easily as 64 reeds. This works to my advantage. On the other hand, at the top, the reeds are relatively short for their pitch and the result is that they far less malleable and "controllable" than do the same pitched reeds on either a 64 or a standard 12 hole. This is something in which I don’t find any advantage. I prefer the longer reeds and feel they act more "naturally" in the air stream allowing you to control your pitch and timbre much more.
As both an experiment and a possible solution, I have tried several tenor models custom designed to fit the lower 12 holes of 64 reeds as opposed to tenor reeds to see what the effect would be. I will admit that the 64 reeds feel more natural to me on the bottom than the tenor reeds do on top. I can adjust to the long 64 reeds at the bottom easily as I have played 64's and standard 12 hole instruments for a long time. The difference between the relative size of the reed and the pitch between the standard or 64 and the tenor tuned is much more drastic on the small reeds of the very high end and presents a greater challenge for me. So, the use of 64 reeds on my 12 hole tenor has turned out to have positive effects. Siegfried Naruhn was the first person to make me one of these and his CB-tenor with 12 holes of 64 reeds is a tremendous instrument. This is one of my favorite chromatics in my collection. Bill Romel also fashioned a Virtuoso chromatic for me that fits the lower reeds of a 64 in 12 holes.
My ideal instrument would probably have a mixture of reed lengths. I would take advantage of normal tenor reed lengths at the bottom and extend my slots to fit the 64 reeds or standard 12 hole tuned reeds towards the top. This would provide reeds that are "not too long" at the bottom and "not too short" at the top with a fairly even response throughout the instrument. Sort of like the Goldilocks story set to reed lengths. Of the three tenor instruments I play the most, the Renaissance, the CB-tenor and the Virtuoso tenor, only the CB has the special 64 reeds. The Virtuoso I use most is the "Gold" Virtuoso with regular tenor reeds and I actually prefer it to the Virtuoso with 64 reeds for its particular sound ;-). The Renny sports regular tenor reeds. S o, I haven’t found that the experiment’s results would make me suggest to all tenor players to get special reeds cut from the bottom of a 64 plate. However, I am pleased with the results of these plates and I think a re-examination of the traditional tenor reed length/plate is definitely in order. I really love the "feel" of the top of the CB-tenor and Silver Virtuoso and would enjoy that advantage on all my harps, but the "Gold" Virtuoso and Renny also maintain qualities that I appreciate - including a really "smooth" low end that I would also like to guard. Thus my suggestion of a "hybrid" set of sizes.
I also urge more people to try tenor instruments out ;-). A quick plug for the good old tenor is always a must. I find it is in the perfect range for jazz. It not only has enough room at the top to play nearly every melody and produce beautiful solos, but it reaches down to the areas of tenor sax and trombone where one can play harmony parts as well. Since most of the blowing instruments used in jazz stick around these lower regions it seems to "fit right in". On the higher octaves I find myself gravitating towards a style that is similar to flute or right hand piano rather than the sounds of trumpet and sax that I find most expressive in my personal jazz interests. So, don’t forget to try out those tenors!
