I need some way to sustain the tone of a glockenspiel
I have a project that requires a glockenspiel, but used in a very special
way: I need to sustain its tone without decay and resmacking the bars. Is there any way to do this? Thank you, Earlee |

I need some way to sustain the tone of a glockenspiel
Can't you just sample the sound and "loop" it?

Live or in the studio? I bet you could put piezo buzzers on the bars, connect them all in parallel up to an amp, connect it to a microphone. You'd have some trouble arranging things so it doesn't break out into constant oscillation and you may have to have someone riding the gain, but you could get one note to last for hours I suspect. Like a mechanical E-bow, sort of. It would be ugly. The other alternative would be to use a vibraphone and unplug it... plenty of sustain. Even more if you mike it and compress the crap out of it. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Thank you, Earlee There is a guitar pedal by electro-harmonix called Freeze. Press the button at the point you want to hold, and it produces a note or chord that sustains as long as you want it to. d |

Thank you, Earlee You could try using a reverb that has an 'infinite' or 'hold' setting. Electro Harmonix make a pedal called 'freeze' that does the same kind of thing. It wont be as fun or versatile as a mechanical way of making it sustain though. |

Thank you, Earlee I've seen xylophone players 'bow' the ends of the bars with a bass bow, you don't get the same attack but you do get long sustain. |

It takes a while to be able to do it smoothly without a noticeable break in the sound, however. Also, with a horn, any electronic enhancement to your sound must necessarily be accompanied by the sound that eminates directly from the instrument itself, unless you are in a soundproof booth. |

I don't know if he wants a repeated strike at some frequency, or a continuous ringing without diminishing volume from one strike of the instrument. If the latter, then I don't know how to do this mechanically, although bowing with some sort of rotary "bow" device might work. |

I remember from marching band days that they are suspended somewhat so they'll sustain when struck but they're so light and small vibrating them would likely vibrate them into the support and not in freer space. What I mean is, they don't have the physical resistance that a vibes bar has to vibrate in place. Certainly worth a try, though. Maybe very slightly, barely touching it, would dispel that negative theory and make a soft sustained sound. Reminds me of a recording of a prepared piano piece decades ago I was assigned to, which seemed like it was going to sound awesome, and it sort of did, if you liked the sounds of the drills and other string exciters that were unintentionally completely overshadowing the strings : ) |

If it is in marching band style (Bell Lyra) t would be easy to bow, but most Glockenspiels are "Orchestral Bells" in a wooden case then some improvisation wold be in order. The idea of using a motor with a wheel on it would work, but I would use a motor that is slow and a felt or leather wheel with rosin on it to keep the note excited. This would be along the lines of a Hurdy Gurdy. |

I used to have one with a variable speed motor, and I could slow it down until it was almost silent, but still had reasonable torque. |

Would that work? Steve King There is an instrument that does that with multiple rotating glasses of different sizes, on a table. The player stands over them, dips his fingers in a small bowl of water, and then touches them to the edge of the different rotating glasses to make the sounds. Using both hands, he can produce two notes at a time like a violinist can. It produces very interesting sounds, but a bit weak in volume, but I suppose that could be boosted electronically. |

Exactly how long a sustain do you need? And is this for live work, or
a recording? Peace, Paul |

The problem with making a loop from a glockenspiel, as opposed to a sax or violin, is that it's a one way street with no loitering, so to speak. The only way to get a loop is to take such a small section of the waveform that you end up practically just taking a few single cycles, and it doesn't sound any better than if you just took one. There would be many cycles to choose from but you can't use much else in either direction. So you have this static sound like an organ so you give it the attack you want (you could use the original) and then the rest of the ADSR, and you've ended up recreating, resynthesizing, something to resemble the characteristics of the original instrument you took it from. I guess it depends how much it has to sound like a sustained glockenspiel, or just a sustained kind of glock-like sound. Or if it's for a concert and the idea is to not have the musician pushing their index finger down on a synth keyboard. |

You might glue a pietzo crystal to the underside of each bar in the glockenspiel, and then feedback the audio signal from each bar to the crystal of that particular bar, creating a sort of combined electrical and mechanical reedback, which, if properly adjusted could sustain the sound indefinitely. |

Lots of treble and no bass is bad, because with no bass the hearings own protection mechanism fails to trigger. I recorded music with glockenspiel recently, Rutters Requiem, it took multiband compression to get the 12 kHz from the glockenspiel in line with the choir and the ensemble in a manner that made it playable on consumer equipment. Respect to the guys that could make it appear reasonable on vinyl, of course the analog tape would have helped them! Kind regards Peter Larsen |

I need some way to sustain the tone of a glockenspiel
I thought of this a few days ago (which shows how long this thread has gone
on). Would a sustained glockenspiel tone -- which, of course, would be missing the initial attack and subsequent decay -- even be recognizable as a "glockenspiel" sound? If not, what would the point be? I suspect the OP wanted the sustain /after/ the initial stroke. |

I need some way to sustain the tone of a glockenspiel
This thread has become kinda pointless since it appears the OP has
left the building. But it's still a fun and educational discussion!

I've looped things like struck bars with success, encompassing several seconds within the loop to sound more natural. A glock doesn't always decay in a purely linear fashion. Especially the larger bars. The Seamless Looper program I mentioned uses a very smart algorithm to find the loop points. Not just based on zero crossings, but also "internal" cyclical variations such as vibrato on a cello or violin. The chance for success also depends on where in the decay you loop. If the OP was satisfied for the loop to start after five seconds when the tone had decayed by 10 dB or whatever, at that point the tone is closer to a pure sine wave. So looping only a few cycle would not sound so bad or unnatural. --Ethan |

Yet another hit-and-run. |

Instead of hitting it with a mallet, you use an angle grinder on it. Would a Dremel with a grinding wheel work? I think that's definitely the way to go. *But the problem is that a glockenspiel's bars are small and not as meaty as a vibraphone's. *I remember from marching band days that they are suspended somewhat so they'll sustain when struck but they're so light and small vibrating them would likely vibrate them into the support and not in freer space. *What I mean is, they don't have the physical resistance that a vibes bar has to vibrate in place. * Certainly worth a try, though. Maybe very slightly, barely touching it, would dispel that negative theory and make a soft sustained sound. Reminds me of a recording of a prepared piano piece decades ago I was assigned to, which seemed like it was going to sound awesome, and it sort of did, if you liked the sounds of the drills and other string exciters that were unintentionally completely overshadowing the strings *: * ) We've all probably excited a sustained tone from a crystal goblet by running a dampened finger around the edge. *Would that work? Steve King There is an instrument that does that with multiple rotating glasses of different sizes, on a table. The player stands over them, dips his fingers in a small bowl of water, and then touches them to the edge of the different rotating glasses to make the sounds. Using both hands, he can produce two notes at a time like a violinist can. It produces very interesting sounds, but a bit weak in volume, but I suppose that could be boosted electronically.
