The Harmonium "Sustain" Test

Uncategorized Jun 03, 2022
 

Here's a video where I compare the sustain on four different harmoniums.

HARMONIUM SUSTAIN

A good harmonium ought to sustain a 2-note chord for 4-7 seconds. Any less than 4 seconds and you'll have to pump constantly, which is a distraction.

How does your harmonium stack up? Here's a four step "sustain test" that will give you useful info on the state of your instrument. 

  1. Check to make sure the hooks on the sides of your instrument are hooked. If not, the instrument will leak air, which will decrease your sustain.
  2. Play the notes Middle C and Middle G on your keyboard. Be sure to play the notes in the middle of the harmonium, not at the top or bottom of your keyboard.
  3. While holding down these two notes, pump vigorously three or four times (just once won't do).
  4. Stop pumping and continue holding the two notes, then count the number of seconds your instrument sustains those two notes. 

As a benchmark, a Bhava Mini harmonium will have a 4-7 second sustain. You can expect a slightly lower number for a smaller instrument (like a Bhava Lite), and a slightly higher number for a larger instrument (like a Bhava Classic).
