Pitch of voice problems are wide spread and becoming more of an issue in recent years. All singers who are paying attention realize the impact of singing off pitch and most take care to craft their voices and follow good practice principles. However, it can still be challenging to correct pitch of voice problems without good feedback. For the past forty years or so, singers could record themselves with a tape recorder and then listen to their performance. Prior to this, few singers could afford the use of expensive recording equipment. Even earlier in history, singers relied on feedback from a direct listener, who could have a good ear for pitch or not.

Fortunately, modern singers can use singing software to provide immediate real time feedback about their pitch of voice and begin making corrections immediately. The singing software available today can graph the singer’s pitch and provide challenging vocal patterns as exercises. Often singers will develop an awareness of specific problem areas based on the scale degree or interval between notes. For example, when singing a simple major triad, a singer may notice that they are consistently flat on the third scale degree. Or, when singing an octave arpeggio, the singer may notice they consistently overshoot the octave. This type of pattern is difficult to detect without the use of singing software.

Voice pitch is the frequency heard by the audience with a vocalist sings. By contrast, the frequency heard by the singer is slightly different, due to the physical signal path of the audio wave passing through head membranes and bone. One could correctly argue that the audience perspective is arbitrary and that the room of the listener affects pitch as well. While there are discrepancies in perceived pitch depending on the position of the listener, the most common deviation in pitch is between the perception of the singer and that of the listener, or microphone.

New singing software and hardware can help correct for pitch problems in real time performances and improve the overall quality of a show. However, this type of manipulation can backfire and it is possible for a very poorly sung note to be so far off that the software moves the pitch to the wrong note entirely. Also, this type of correction does not help the vocalist become a better singer, rather it can reinforce bad vocal performance habits. Some of the latest singing software is designed to be used by vocalists during practice sessions and actually helps train the singer to sing on pitch, thereby eliminating the need for real time correction during a live performance.
