Ondophone On Point

Ondophone On Point

The name Ondophone is a mash-up of two instruments, the Marxophone, and the ondes martenot. From the Marxophone, [Wintergatan] borrows the spring-loaded hammers, which repeatedly strike a string once activated. The ondes martenot loans its Theremin-like sound and ability to lean back on western semi-tone notes. Mating such different instruments requires a team, and much like the name, it produces a splendid blend.


At the left-hand side of the Ondophone, we see the spring-hammer battering away on a steel string whenever the neck moves up or down. Next to it is an Ebow that vibrates a string with an electromagnet and can maintain a note so long as it has power. Hidden within the neck are magnets to demarcate semi-tone locations, so it’s possible to breeze past them for a slide sound or rest on them to follow a tune.


The combination of intermittent hammering and droning lends well to the “creepy” phase of the song, which leads segues to the scope-creep that almost kept this prototype on the drawing board. The video talks about all the things that could have been done with this design, which is a pain/freedom we know well. KISS that Ondophone headline act goodbye.


The ondes martenot is an early electronic instrument, so we’ve some high-tech iterations, and if you haven’t heard what’s possible with a DIY Ebow, we will harp on you.
