Twitter Bot: UkeChord

I would like to introduce you all to my new creation UkeChord. UkeChord is an automated Twitter robot who will send you ukulele fingerings for any chord you request. Please share your thoughts or improvements in the comments below.

Goal: To offer Ukulele chord fingerings via text message.

Preparation:

  1. Follow Twitter user “ukechord
  2. Configure Twitter to forward direct messages to your phone.

Getting a chord fingering:

  1. Text Twitter (40404) with: “@ukechord” followed by the chord name.
  2. Receive chord fingering.

Below are the chord names it understands. C can be replaced by any note sharp (#) or flat (b):

Chord Notes
C (Root, major 3rd, perfect 5th)
C7 (Root, major 3rd, perfect 5th, minor 7th)
CM7 (Cmaj7) (Root, major 3rd, perfect 5th, major 7th)
C6 (Root, major 3rd, perfect 5th, major 6th)
C9 ([Root], major 3rd, perfect 5th, minor 7th, major 9th)

It may be able to figure out other chords, but it is guaranteed to understand these.

Barbershop Multitrack Tag: Overtone experiment / robot quartet

Edit: Most of the explanation I came up with for this turns out to be wrong. I will update when I understand more thoroughly.

I recently had a conversation with my dad regarding “overtones” (a note that can be heard in a chord that is not acutally being sung). He informed me that what we in the barbershop community call overtones can be more accurately called sum tones, or as wikipedia calls them combination tones. The explination is that all tones, or sounds that we percieve as a single note, are actually comprised of that note, and an infinite number of notes above it (overtones). These notes are arranged according to the harmonic series: the root and octave above, the fifth above that, the root above that, the third above that, and so on with the intervals between these notes getting smaller as we Read More…
