    I am very concious that the older instruments such as the conn 80a, - I use that simply as an example, - lack any adjustable slides the slides can be preset but not adjusted during play, there is no ring or trigger on these early jazz horns.

    I agree Mike, to improve correct slotting a slide can be adjusted to tune the note as we play it. This is necessary as the notes of the harmonic series are simply not in tune with each other due to the acoustic limitations of a fixed tube or collection of tubes such as a trumpet.

    So how do we play in tune on an instrument that cannot be adjusted as we play. The answer of course is by lipping. This is made easier in a looser slotting horn and perhaps the point of it.

    Are we seeing the result of legacy instrument design here. Loose slotting horns being the children of the jazz horns that required lipping to play in tune. A tight slotting horn would have been somewhat difficult to handle with little ability to lip.

    I put it to the members that the wide acceptance of instruments with freely adjustable slides may well have resulted in the widespread growth of tighter slotting instruments.

    I plead guilty here to building a house of cards from assumptions and table this for members to ponder upon.

    We must never forget that zombies are extremely difficult to kill, I have armed myself with a silver bullet and a wooden stake just in case either is effective but as I understand it the only thing that will kill a zombie is destroying its brain.

    I feel that I am uniquely fitted for the task of destroying a brain by word power alone and I therefore will continue to post my usual bullshit gibberish until all zombies are dead.

    I like a tight-slotting instrument for the type of playing that I do, but it needs to slot the notes not only centered, but in tune. That aspect has been somewhat left out of the discussion. It's really nice to have an instrument/mouthpiece combination that when you play a note, WHAM!, it's right there - centered, full, and in tune. Of course, some notes still have to be favored a bit due to the inherent design limitations of a valved instrument, situational tuning with an ensemble, and with certain chords. If you have a horn that doesn't have the greatest intonation but has loose slots, it can be lipped into tune easier. However...a lot of lipping to pull notes into tune leads to more playing fatigue and less endurance.

    You mention an aspect that hasn't been previously mentioned in this thread and I think I have one too. I have seen & heard demonstrations on slotting and how that was directly affected by the mouthpiece gap. I have seen several references to mouthpiece & horn combination but nothing about gap. Could it be when you find a better working mouthpiece for the desired result it is actually a difference in gap ?

    Yes, I'm a firm believer that gap can affect a lot of things on a trumpet, but it varies with the trumpet (and maybe the design of the mouthpiece, too) - some aren't affected by gap as much as others.

    A term used regularly in the Casino.
    If someone asked what you are going to play.
    As in, " I'm going slotting "

    For me slotting is just how true a tone is. If there's wiggle room on a note, I consider that loose slotting vs. little wiggle room.

    Slotting is all about the "Q" factor.

    I think that there is some universal wishful thinking here. The harmonic/partial series (except for octaves of the fundemental) is out of tune compared to "just" or well tempered tuning. The fifth (3rd and 6th partial) is too high, the third (5th partial) is too flat as is the 7th partial (forgetting notes above high C). This is true for any and every trumpet. The design of the instrument trades off various things to make playing in tune possible and easy. WE ALWAYS ADJUST TO OUR SURROUNDINGS!

    Now, in physics we define a quality(amplitude/efficiency) of resonance by the symbol Q. Technically we could define the physical resonance of the horn as slotting - but there is much more. How we hear ourselves has a lot to do with what we think that the horn is doing. A trumpet with more feedback appears to "slot" better when in fact it is leaking more "resonance" to the players ear instead of the audience. Certain mouthpieces that promote a brighter sound also seem to "slot" better.

    So, my definition of slotting for the trumpet world is:
    What a player subjectively feels in regards to the security of "hitting" notes throughout the range with a clear tone.

    In my world technical arguments are mostly wasted because of the factor "I believe"...
