My neighbours are great people, I live in a side-by-side duplex. I practice in the basement, and I’ve told them that I will not practice past 8 PM in the evening. With my schedule this can be trying at times to get everything done and my routine done by 8. I do have a quiet mute that I use if I play past 8, and even though the mute can have it’s advantages, the back-pressure sometimes gets annoying, and you just want to play “Open”. So I went to the store and bought a good-sized plastic storage bin, and a roll of 2 Inch thick foam. I lined the bin with the foam and cut a hole in the end of it, so I can get my bell into the bin easily. Taped the box to a music stand and positioned it so I can easily put the bell inside at my normal playing position. Geez, my better half can’t even hear me when she’s just above me in the living room and I’m playing wide open downstairs. Plus the horn plays with Normal backpressure ! I’ve read lately by a few of you that you find it hard to find a place to practice and not bother anyone, This is the ticket to wide open playing with no worry about bothering the neighbours. Now I’m wondering what it would be like to record this way placing the mike inside the bin, talk about a flat signal !!!! I will try recording soon to see what it sounds like. Just thought I would pass this on to those who worry about bothering neighbours. I need to give this thing a name !! Mobile studio….trumpet silencer….Practice box….Padded room for trumpet players !!!
