I mentioned in my most recent post that true tone deafness does not exist except where actual deafness exists. since then I've researched the concept a bit further. According to research, my statement was correct, but my rationale for it may have been somewhat flawed, or at least not in total accord with the current school of thought as espoused by the expert.
True tone deafness does not exist separately from actual deafness primarily because almost anyone, once taught the musical concepts of "higher' and "lower" in relation to pitch, basically anyone who can hear the pitches can determine the higher or lower of the two except possibly with intervals of only one-half step. Furthermore, few people need to be taught the concept of "higher" or 'lower" in pitch, and nearly all can differentiate between higher and lower even with one-half-step intervals. still, it would be unfair to classify a person as possessing the quality f tone deafness without first ascertaining a basic understanding of the underlying concepts.
I stated in my most recent blog that most people can hear when others sing or play an incorrect note. Such is apparently not always the case. I found a video of a young woman who plays the clarinet. She sometimes adds flats or misses sharps. She doesn't hear the melodic changes (usually not for the better) that are created in doing so.If you know the hymn she is playing, you will hear the A-flat concert (B-flat on clarinet) that should be A-natural concert (or B-natural on clarinet). I would like to have selected a more well-known hymn for non-LDS readers, but for some reason, the young woman who made this video favors they hymns in the LDS hymnal that are not in common with other denominations. C'est dommage!
I do not own this video. I hope that I have offended no one in borrowing it.
