Pitch and timing do not describe everything in a sound. **Timbre includes a sound’s spectral content and how it develops over time. Texture concerns how musical parts combine.** This lesson first changes the sound of one note, then changes which parts are present in a short ensemble. Allow about twelve minutes. Use a comfortable volume; headphones may make the low layer easier to follow. ## One pitch, two dimensions of change Compare **Pure · quick** and **Rich · quick**. Both have the same fundamental frequency and attack time. Next compare **Rich · quick** and **Rich · slow**. This time the harmonic recipe remains the same, while the onset becomes more gradual. **Same fundamental, different sound** All tones have fundamental 261.63 Hz and duration 1.4 seconds. Pure uses one partial; rich uses relative amplitudes 1, 0.5, 0.3, 0.15. Rich slow changes attack from 4 to 250 ms. The fundamental is about 261.63 Hz, corresponding to C4 in our tuning. The pure tone contains that single frequency component. The richer tone adds components at two, three, and four times the fundamental frequency. These integer-multiple components are **harmonics**. Their relative strengths change the shape of the repeating waveform and the resulting timbre. The bars show the recipe’s relative amplitudes: 1, 0.5, 0.3, 0.15. A harmonic with half the amplitude does not necessarily sound half as loud. Both versions use the same master volume setting, but spectral changes can also change perceived loudness. Listen for the tone color as well as any difference in apparent loudness. The **attack** is the beginning of the amplitude envelope: how quickly the sound rises from silence. The quick example takes 4 milliseconds to reach its peak; the slow one takes 250 milliseconds. Both notes last 1.4 seconds, so the slow attack leaves less time for decay. The envelope describes loudness-related amplitude through time; the spectrum describes frequency components. They answer different questions. | Keep fixed | Change | Listen for | | --- | --- | --- | | Fundamental, duration, quick attack | Harmonic amplitudes | Difference in tone color | | Fundamental, duration, harmonic recipe | Attack time | Sharp versus gradual onset | | All remaining parts in an ensemble | Presence of one part | Difference in texture and musical function | ## Instrument timbre
What gives an instrument its characteristic sound? An instrument’s characteristic sound comes from several features working together: its changing spectrum, resonances, breath or bow noise, and the way a performer begins and ends each note. Harmonic balance and attack are two parts of this richer sound. Many pitched musical sounds have harmonic components, but not every sound has this structure. Some percussion is strongly inharmonic or noise-like. Even perceived pitch need not require energy at the fundamental itself. Here the fundamental is present in every version so the comparison stays straightforward.
## Hear a part by taking it away The next original four-bar passage contains four layers: an upper melody, a low recurring C, repeated three-note chords, and a high regular pulse. Start with **Full mix**. Follow the melody once, then replay while following the bass. Your attention changes even when the score does not. Now remove one layer at a time. Predict what should disappear before listening. Return to the full mix between comparisons so you have a stable reference. **Hear the layers by removing one** A four-bar original contains melody, bass, repeated triads, and a high pulse. Compare the full mix with versions missing bass, melody, chords, or pulse; retained events do not change. Removing the bass takes away the lowest repeated line, but leaves the chord layer. Removing the chords still leaves bass pitches, so harmonic clues remain. Removing the high pulse does not erase the beat: the other parts still have regular onsets. Removing the melody preserves the accompaniment’s timing but removes the changing upper tune. The chart shows black bass marks, lighter chord marks, and accent-colored melody and pulse marks. Height represents pitch; it does not rank a part’s importance. The remaining parts keep their notes, rhythms, and dynamics. The total sound naturally becomes less dense when one layer disappears. A **texture** is a way parts combine: a single unaccompanied line, a melody supported by chords, or several independent lines are different organizations. Our full mix is a melody with accompaniment, commonly called a homophonic texture. Four layers do not automatically mean four independent melodies. [Musical texture](https://musictheory.pugetsound.edu/mt21c/Texture.html) ## Check the distinction Imagine two edits to a recording. In edit X, every part remains, but the lead sound changes from a sharp onset to a soft onset. In edit Y, the lead keeps its original sound, but the bass is removed. Which most directly changes timbre, and which changes the combination of parts? Can edit Y also change your impression of the music’s weight?
Read the answer and what the labels leave open **X primarily changes the lead’s timbre through its envelope. Y changes the texture by removing a part.** Yes, removing the bass can also make the passage seem lighter. A perceptual description can reflect several musical causes. These are not mutually exclusive editing categories. A real arrangement may change instrumentation, register, dynamics, and the number of parts together. Start by identifying the controlled change, then describe its effect without assuming that the effect has only one possible cause.
Choose a familiar recording and listen three times: once for the lead, once for the lowest part, once for the regular timekeeping sounds. Notice when a part enters or drops out. Those entrances can mark larger sections, which brings us to the final lesson on repetition, variation, and form.
