The largest and lowest saxophone. It weighs around 90lbs, there are only 4 in the United States, it's pitched in Eb, and it is the most awesome thing in existence. Most sax players say their lives would be complete if they could play it.
Holy s***! It's a contrabass saxophone! That guy playing it is one lucky bastard.
Likely one of the lowest members of the Saxophone family. Stands at around 6 1/2 feet tall and weighs around 45-50 pounds. Less than 30 are believed to exist worldwide.
Has a wide range and a broad, mellow tone. Lower notes can be low enough to sound alike to human ears. Generally not specifically needed but a nice addition to most symphonies, if they can find one...
Should you go looking for this elusive beast, a good place to start would be the Eppelsheim company based out of Munich. Retail price is will set you back about $25,000-$30,000.
Guy 1: What is that you're playing?
Guy 2: It's a Contrabass Saxophone.
Guy 1: Whoah...
Guy 2: Yup. I had to mortgage my house and use my kid's college money to afford it, but it was soooo worth it.
