Perfect Pitch vs. Relative Pitch And What You Can Do About It!

Pitch is a fundamental aspect of music and speech perception. It refers to the perceived fundamental frequency of a sound, which determines its musical note or speech intonation. However, the perception of pitch is not solely determined by the physical properties of sound waves but also by the processing of neural signals in the human brain. And if you’ve ever been told you’re off-pitch, read below to see how to work out the solution to the conundrum no musician would ever consciously choose!

3. What Is Pitch?

The human brain has several regions that are specialized in processing different aspects of sound perception, including pitch. The auditory cortex, located in the temporal lobe, is the main region responsible for analyzing the spectral and temporal features of sound stimuli. It receives input from the cochlea, a spiral-shaped organ in the inner ear that converts sound waves into neural signals, and processes this information to identify the pitch, timbre, loudness, and location of the sound source.

The perception of pitch begins with the detection of the fundamental frequency of a sound, which corresponds to the rate of vibration of the sound wave. For example, a sound with a fundamental frequency of 440 Hz is perceived as the musical note A4. However, in complex sounds such as speech or music, the fundamental frequency is often accompanied by a series of harmonics, which are integer multiples of the fundamental frequency. These harmonics contribute to the timbre or quality of the sound and allow us to distinguish between different musical instruments or voices.

The processing of pitch in the brain involves several stages of neural processing, including the extraction of spectral and temporal cues, the integration of these cues into a pitch representation, and the comparison of the pitch representation with stored templates of musical notes or speech intonations. The perception of pitch is influenced by several factors, including the complexity and duration of the sound stimulus, the presence of background noise, and the listener’s attentional state and musical training.

2. Who Has Perfect Pitch?

Pitch perception is a complex and multifaceted skill that varies among individuals. Some people have a remarkable ability to identify and reproduce musical pitches with high accuracy, known as perfect pitch or absolute pitch. Perfect pitch is a rare ability that is estimated to occur in less than 1% of the general population. However, the prevalence of perfect pitch is higher among musicians, particularly those who started their musical training at an early age.

The origins of perfect pitch are not well understood, but they are thought to involve a combination of genetic and environmental factors. Several studies have suggested that perfect pitch may be inherited as an autosomal dominant trait, meaning that it is more likely to occur in individuals with a family history of perfect pitch. However, the genetic basis of perfect pitch is not well established, and it is likely to be influenced by several genes that interact with each other and with environmental factors.

Environmental factors that may contribute to the development of perfect pitch include early musical training and exposure to a tonal language, such as Mandarin Chinese, which has a pitch-based system of lexical tone. Several studies have shown that individuals who started their musical training before the age of 7 are more likely to develop perfect pitch than those who started later. This suggests that early musical training may enhance the neural plasticity of the pitch processing system, allowing it to develop more precise and stable representations of musical pitches.

In contrast to perfect pitch, most people have relative pitch, which refers to the ability to identify and reproduce musical pitches in relation to a reference pitch or key. Relative pitch is a more common skill that can be developed through musical training and practice. It involves the ability to perceive and remember the intervals between musical notes, which are the differences in pitch between two notes.

The development of relative pitch is thought to involve the formation of neural templates or mental representations of musical intervals, which are stored in memory and used to identify and reproduce pitch sequences. The formation of these templates is influenced by several factors, including the complexity and frequency of the intervals, the context in which they are heard, and the amount of training and practice.

1. How Do You Improve Your Pitch?

Being able to maintain an accurate pitch is essential for any musician. The top pitch-enhancing technique is actively listening to a wide array of songs. Make it a point to be an observational listener and use your critical ear. Focus on individual instruments or voices and try to identify the pitch of each note. This will help train your ear to recognize different pitches and intervals.

This leads us to, interval training. Interval training is knowing the distance between two notes on a scale; how the second note relates to the first, and the third to the second, so that when you want to actually play those notes, you can. You know how far above or below each note the next one should be. Learn the sound of different intervals (e.g., major thirds, perfect fifths) by memorizing their unique characteristics. This will help you identify and reproduce these intervals more accurately.

Similar in value to interval training is pitch matching. You can both sing along to other vocalists or match an instrument you have on hand to the notes you hear in a popular recording. Choose a song you enjoy and sing along with the recording, focusing on matching the pitch of the original singer. This will help improve your vocal pitch accuracy. For instrumentalists, play along with recordings, focusing on matching the pitch of the original performer. This will help train your ear and improve your pitch accuracy on your instrument.

And last but not least, use your phone/microphone to analyze your shortcomings. When you regularly record your practice sessions and performances, you will allow yourself to objectively assess your pitch accuracy and identify areas for improvement. Listen critically to your recordings, taking note of any pitch discrepancies. Use a tuner or a reference recording to help pinpoint the problematic areas. When you can’t stand that voice of yours, you’re likely hating the off notes, and you’re aware of your poor technique. Aim to reach the day when you confidently play back your recordings and enjoy what you hear!

To summarize, the perception of pitch is a complex and multifaceted skill that involves several stages of neural processing in the human brain. Perfect pitch is a rare ability that is thought to involve a combination of genetic and environmental factors, including early musical training and exposure to tonal languages. Relative pitch is a more common skill that can be developed through musical training and practice, so there’s hope for you to still be a good musician if you’ve been told you sing off-pitch!
