Tremoloa

[2] Musical collective Broken Social Scene features the instrument in "Tremoloa Debut."

The instrument is also featured sporadically on The Magnetic Fields' album 69 Love Songs.

The tremoloa simulates the tonal effects of the Hawaiian steel guitar by passing a weighted roller stabilized by a swinging lever termed an arm, along a melody string.

[3] Following, moving the roller after plucking creates tremolo, an effect which gave rise to its name.

Additionally, the tremoloa possesses four chords (C, G, F, and D major), to strum out the harmony.
