Wow, that sounds more complex than the piano! Would the pedals and levers also have a flex to them? For example, if you wanted to move from C Maj to Db Maj. Would you press the lever/pedal just a hair up to increase the string tension?
Or, do the both of pedal and levers act as sort of an On/Off switch?

Rio, if I understand you correctly, the bar hand in its horizontal line can play a C Maj scale? Then, by moving a lever and or pedal it changes the string tension to fit say an F chord/scale? You mentioned a C scale. Is the instrument tuned to a C scale before moving any pedals or levels? In other words, if I were to not lay the bar down on the strings and not touch any of the pedals or levers I should be able to play a C scale like the way I would arpeggiate a chord on a guitar for example?

Next, you mentioned how you mix the use of the pedals and levers. Does one represent flat/sharp while the other represents minor/major?

Lastly, please check my logic here. Beginning with no pedal/lever movement, If the open string is "G". I press down my bar on the the second fret of that string now the note becomes an "A". Next, I move the lever/pedal to the F position. Now, the open string that was formally "G" has now shifted to "Bb". I press my bar down on the second fret and now I have a "C". Is that logic correct?

Sorry to be so inquisitive. Thank you so very much for taking the time to address my questions. I have always had a fascination with this instrument. While not knowing anyone who owned one in addition to the local music stores never having one in stock to toy around with, I have not had anyone to answer my questions. I want to purchase one some day. Before I do, I would like to know if it is something I can navigate. I do play piano, percussion as well as guitar. In addition, I do understand music theory to transpose and navigate around.

Am I getting warmer?
Thanks
