Tombo Pocket Bass harp: re-tuning

Anything apart from the two mainstream default harmonicas (Solo-tuned fully-valved chromatic, and un-valved Richter 10-hole diatonic). Alternate tunings, different construction, new functionality, interesting old designs, wishful-thinking... whatever!

Tombo Pocket Bass harp: re-tuning

Post by IaNerd » Fri Jan 12, 2018 5:39 pm

NAME: Tombo Pocket Bass harp: re-tuning

The standard Tombo Pocket Bass harmonica has the following notes: D/F -- C/A -- G/E -- D/B -- A/F#. Research suggests that, among popular songs in the Western world, the most-used accidentals are F# and C#. I added a C# to the Tombo.

WHEN/HOW: January of 2018.

Of the original natural notes, only the D is repeated. I re-tuned the lower left D to become a C#. This project was easy to do and the resultant harp works very well.

No. The A besides the D is duplicated too.

If you want to break the order of the notes in fifths from left to right and in thirds from the lower row to the upper row, then you can do so. You even can retune one of the A's into a G# or a Bb. Then you win one more accidental, that is used quite frequently. Anyway you will not get a fully chromatic instrument by doing so. But you will partly loose the original tuning pattern, that provides a more smooth and intuitive playing in accompaniment of songs in C and G, for which this pattern is thought for, especially when increasing the speed.

And btw, you can take an Easttop Mini Bass (if you do not mind welded reeds). Following the same pattern of the layout like the Tombo, this has furthermore a Bb (left of the F) and a second G, one octave higher than the other (left of the D in the lower row). Then you could retune some more notes to gain one or two more accidentals. But you get an even more chaotic and less intuitive order of the notes. And a fully chromatic instrument it is not yet either.
