Auto-tune is a well understood concept, a waveform is
analyzed then pitch shifted to the nearest neighbor in a
fixed scale.
Imagine an instrument, in this case the humble tuba. On
the main tuning valve, a servo motor is attached. A
calibrated reference microphone would be placed in the
bell.
For those of you who know brass instruments certain
notes are natively out of tune due to the harmonic
principles. High level players will adjust tuning slides to
compensate for these out of tune notes.
This reference microphone would listen to the frequency
and match it to the closest note by automatically
adjusting the main tuning slide faster than any human
could. Going to your child's recital would no longer
require earplugs or cotton balls!
For extra credit you could add limit switches under the
valves, so when you did valve 2+3 on a tuba or trumpet it
would automatically compensate before the note is
sounded.

This could also be done on string instruments by
tightening or slackening the strings (auto tremolo?)
and could be done on a piano in a similar fashion
albeit with more difficulty |

When I saw the title, I thought this might be an idea for a automated Tuna and Sheep duo device. |

I bet some really wild guitar effects could be created by
servos that could be used to alter the tension of individual
strings at the touch of a button; sort of like a single-string
digital whammy bar. |

You could really freak out a trombonist by fitting
one of these surreptitiously. |

There's a tuning valve on a trombone? I thought they just
had a spit valve. |

The Good Fairy Jenny says she's not sure. |

Trombones typically have a tuning slide, separate
from the main slide, that's what would get
tweaked. The alternative would be to have it
mounted between the handle and the main slide,
which is what I think [MB] was talking about. |

(For the record valve trombones do exist, but
they aren't what you would think of as a
trombone. Also some tenor trombones have an
"F" attachment that changes tuning on the fly,
and that uses a single valve). |
|
| |
trombones tend to have f and even e flat valves to
help with tuning and to reach 5th and 6th position
faster. And yes they have a tuning valve, because
you would still want 1st position to be in tune. |

Ever hear the sour crout band? |

Great for violins if the kids play the fingers correctly. Useless
with clarinets. Fun just thinking of it. Btw today all players have a
digital tooner so kids concerts should be easier on the ear. Are
they? |
|

as someone who played tuba for 12 years:
yes everyone has a cheapey digital tuner, it still
takes years of development before a young player
has anything close to good ears and can play in
tune. Some notes will be naturally out of tune
(2+3 figuring) and thus they will always be out of
tune and require the player to adjust the valve
slide. Trumpets have key rings and can adjust the
tuning on the fly, but that's an advanced
technique. |
|
| |
Very few tuba players adjust their valve slides
while playing, sometimes it's impractical |
|
| |
I disagree. Going to a young children's band concert
requires brass balls for sure. |
