  1. Of course Erik!. I am very grateful to everyone that have participated
  2. In my prototype the hand strap also would remain loose enough to move the hand either up/down or swivelling. But in this context I have found a soft thumb loop would greatly improve the bellows control with scarce affection on hand freedom. Incidentally, I have discovered this system allows to loose the hand strap to the extend you want (well, within a secure margin, of course) because you can easily use the thumb to adjust the entire tension of the system, by spreading laterally the thumb.
  3. Very good example John!. And, indeed, Aaron Marcus slides his hand and also rotate it a litle bit to play two octave buttons simoultaneously (the index finger pressing the lower button). Apart from reaching outer buttons, my initial question was focused to allow the hand to swivell in both directions at some degree. At least for me, it is more challenging to try two octave buttons at time whith the index finger pressing the higher button... With the standard hand strap design, when I try this fingering, my thumb finger does find an obstacle against the point where the strap clamps to the handrail, so I can not rotate my hand in enough degree to reach the desired finger positioning. The "integrated" hand-thumb strap proposal that I am experimenting with allows for this fingering and, due to my hand width, my feeling is as I had my hand "in a glove". Recently @Łukasz Martynowicz showed me a video from @tona , and he seems to have (at least in the right side) both hand and thumb straps in his duet (the hand strap being clamped to the sides of the concertina, instead to the ends of the hand rail).
  4. I also use the air button this way.
  5. An interesting observation Alex🧐!
  6. Effectively!. I have same doubt. ...so... @alex_holden... would not appear necessary/suitable an air button in this case of having bisonoric?🤣
  7. forgive me this time inventor, but I am bit intrigued by the motivation for having bisonoric buttons in a 69 Hayden.
  8. Thank you very much for your detailed and very interesting reply Inventor!😊 This makes sense if I was focused to spanish folk, as tonalities that dominate (conditioned by the pipes in the north, and the "dulzaina" in central Spain) are mostly C, Bb and F. Even actually I don't play so much these, perhaps in the future I would do. Interestingly, I thought about this key before the low Eb. @David Barnert suggested that addition and I would find usefull to have this key instead D#. Re bisonoric: Do you refer to difficulties in order to properly include these keys whiles playing?
  9. I agree Rüdiger. Even more when the decission is in your hands and there are no plans to buy another instrument in the future. Thus, I am taking into account seriously all your suggestions. Thank you!!
  10. 😂 More little wild horses Erik? I suppose this option admitt an amount of possibilities, each of them particularly suited to each player depending on his personal style, as you say. As I know, Litle John has satisfactory experience with bisonoric buttons (my comments being originated in his experience!)
  11. A propos Brian...which key would be your 51th (assuming there is no air button) ?: high C# LFH?, low C# RHS?, high E RHS?, none of these?
  12. Exactly! This is the topic Alex! (I have modified the link, and I think It works properly now) ...And... in relation with bisonoric and air button...¡¡ touché Alex!! 😄
  13. Ha ha...I was just thinking about that question Brian... so this is my following comment: Brian, lately I am thinking about your ( and other valuable suggestions) proposals to add some buttons to a 46 key arrangement , that were explained in the interesting post Don Taylor opened in 2015 ( here ). I like your 50 keys suggestion. But, in relation with these ideas and following the context of " each inch is gold", I'd like to know your opinion with respect to the possibility of converting the low C keys in both sides to combined keys Bb/C (pull/push )
  14. Thank you Don!. Effectively, I am inclined to think in the same line as Jim an Don point out. However , your call to patience is welcome Erik . Not myself Don, instead I think Alex could do the job a little better.... I know jeffries's reed shoes are somewhat smaller than other (even than a short-scaled?? ). But if anyone different from you Erik had told me about 51 buttons in 6 1/4....I didn't consider credible Could you please, Erik, ellaborate a little more about the role of air button when playing low F?
  15. Extremely clear Jim. Thank you very much! !
  16. Sorry because my question wasn't stated properly Don. The question is not to choose between several types of air buttons. Instead is a " to be or not to be" question . As far as a I have read, there is an amount of concertinas lacking air button, air lever or whichever air releasing device. Thinking about a 6 1/4 Hayden duet, where packaging the keys you'd like to include could be more than tricky, I consider perhaps to install an air button wouldn't be a priority.
  17. Not a mistake. Want to be convinced to install an air button in Hayden duet. Context: when every inch is gold
  18. Ops!...problems when uploading files: the upload box shows "Queued"...but nothing happens after that... I will try to use url-links to Drive: https://drive.google.com/open?id=1We9FyCd-OwfyvfAhmcudnSLM1TVPvXEX https://drive.google.com/open?id=1dA_gGWwXwjV5yUosksxS2tw7ORmE2aDt https://drive.google.com/open?id=18pvrFnpoRQYuN0l7ORPV_qg2K3TV7YN-
  19. Perhaps you will find usefull this pdf about chordings that Brian Hayden wrote: " All-Systems Duet Workshop Tutor ", which you can find here I find particularly usefull just the last page!!, as points out to a more general focus in accompaniment than to the specific duet features.
  20. As an addition to that John says, I use to develop the following steps: - follow the singing line (even during someone is singing, but quietly ) by using a partial melody with only the more bass notes I could reach. -In the bridge you can follow doing this whiles other instruments play the melody. - in some parts of the melody I can shift between playing the main melody as well or try the melody by thirds. I thing the sound of the concertina allows to apply the "less is more" principle , so even doing very simple arrangement the effect will be nice . This applies especially when several instruments are playing in unisonous, so a litle contribution in terms of harmony is welcome. After you had gained more confidence trying simple arrangements, finally, I thing the most funny is getting carried away by the song, and try to develop some inventive as John said (forgive me... but don't worry so much if some dissonance appear as a result..that is not terrific!
  21. Yes Erik, I guess making any swivel in an exagerated way would compromise playing, probably. But that is not what I have in mind. 😇 Neither exagerated swivel nor ultra- complex fingering. I just look for some "minor" adaptations to take certain advantage in comfort and playability, if possible, as finally a compromise has to be accepted when you choose a particular type slant (or not), pr some specifications of the hand bar, or some spacement of keys, etc. I took the second picture quickly this morning, after that I realized some uneven things, sorry: the keyboard is so much slided to the left (it should be centered), and the anchor point of the strap in the thumb end should be a litle more to the left, in a place that results in a more natural fitting to the hand (that would coincide more or less with the end bolt location).
