Instrument Personas in Suno: A Practical Guide and Historical Perspective English translation of #46 for Non-Japanese readers

In this section, I will explain how instrument personas can be used in actual music production while referring to the attached Instrument Persona List.

Before discussing practical examples, however, it is important to clarify a fundamental point.

An instrument persona is not simply a function that changes timbre.
Rather, it is a mechanism that recalls the sound memory of a particular era, and at the same time a choice that quietly defines the composer’s artistic position.

In other words, the question “Which instrument should I use?” is not merely about selecting a sound.
It is also about deciding within which historical lineage you place yourself as a musician.

In the sections that follow, I will discuss several concrete examples.
However, due to space limitations it is impossible to cover every instrument in detail, and I ask for the reader’s understanding in advance.

Let us begin with practical usage.

In Suno, almost every instrument already exists as a preset.
Precisely because of this, deliberately choosing a persona implicitly raises the question: “Why this sound? Why this resonance?”

The individuality and appeal of instrument personas lie primarily in their timbre, resonance, and historical associations.
For that reason, it is generally most effective to place them in musical situations where those characteristics can be clearly perceived.

In practice, this usually means using them as a solo instrument or near-solo presence.

Typical examples include:
• the solo instrument in a concerto
• the piano in a piano ballad
• the trumpet in a fanfare
• the cello in chamber music

Using an instrument persona itself is extremely simple.
All that is required is writing the name of the instrument in the prompt.

For example, suppose you wish to create a piece for violin solo and piano.
Using standard presets, the prompt might include something like:

violin, piano

Now replace these with instrument personas.

Which names you choose is ultimately up to the creator, but in practice this is precisely where musical experience, historical awareness, and artistic sensibility begin to appear.

From my perspective, the very concept of instrument personas seems to originate from a desire to make AI music not merely a form of cutting-edge electronic sound production, but a system capable of entering into dialogue with the history of music itself.
Without such motivation, there would be little reason to introduce a feature called “persona” in the first place.

Certain instruments naturally have strong relationships with particular musical styles or historical periods.
Of course, music has no absolute rules, and there are times when one should compose freely without worrying about such connections.

Nevertheless, composing while consciously acknowledging these relationships can also be a powerful and fascinating creative approach.

Rather than exploring every historical detail here, let us begin with a commonly effective combination:

Antonio Guarneri violin, Steinway Concert Grand Piano

This pairing generally produces stable results.
In my own experience using Suno, I have relied on it many times and it rarely produces disappointing outcomes.

Understanding the relationships between instruments, musical styles, and historical periods naturally requires some musical knowledge.
However, many useful insights can also emerge simply by researching individual composers.

For example:

The pipe organs built by the 18th-century German master Gottfried Silbermann were instruments that Johann Sebastian Bach himself played.
Their sound therefore carries the atmosphere of the very era in which Bach lived.

Silbermann also built fortepianos (early hammer pianos), instruments that appeared during Bach’s lifetime and represented the beginning of the musical possibilities that would later develop into the modern piano.

Similarly, the fortepianos made by Andreas Stein in Vienna evoke the clarity and lightness associated with Mozart’s music.

The pianos of Pleyel et Cie are famous as the instruments on which Chopin created many of his works.

All of these connections between composers and instruments are historically documented facts.
However, what is perhaps even more important is the “memory of sound” embedded within them.

The sounds that composers pursued throughout their lives—their ideals, their emotional worlds—are preserved in these instruments in a certain sense as electronic memories.

To work with such personas—historical embodiments represented through instruments—is therefore very close to retracing the creative footsteps of those composers.

The same applies to French Impressionism.
Érard, Louis Lot Flute, Buffet Crampon, and Leblanc represent the musical culture of that era itself.

These instruments were widely used during the lifetimes of composers associated with that style.

Similarly, Henri Hemsch and F. E. Blanchet were makers of famous French Baroque harpsichords (clavecins).
Historical descriptions often compared the French harpsichord sound to “the ringing of silver bells.”

Summoning such a persona today is essentially an attempt to recreate the acoustic environment of 18th-century French Baroque music.

Another example is Aristide Cavaillé-Coll, the great 19th-century French organ builder.
His organs are closely associated with composers such as Saint-Saëns, Widor, and Fauré.

One might think of the overwhelming organ sound in the finale of Saint-Saëns’ Symphony No.3, or the serene ascent toward heaven in the final movement In Paradisum of Fauré’s Requiem.

What Suno preserves internally as personas can be understood as the memory of those resonances.

From this perspective, it becomes clear that personas are not merely interchangeable sound libraries.
They constantly invite us into a dialogue with the history of music.

Naturally, the examples above represent only a small fraction of possible approaches.
Ultimately, creators are free to combine instruments however they wish.

Nevertheless, historical knowledge of this kind often appears before the composer as valuable guidance.
Whether one chooses to follow it or ignore it entirely is itself part of the creative decision.

Piano Personas

Let us now turn to piano personas.

As many people know, Steinway pianos are widely used today in concerts and recordings across many musical genres.
They possess remarkable versatility and can function effectively in almost any musical context.

In contrast, Bösendorfer, another piano often mentioned alongside Steinway in the classical world, has a somewhat different character.

This Austrian instrument is often described as having a deep and weighty German-Austrian sonority.

When used as a persona in Suno, it indeed tends to produce a powerful and solid sound rather than a light one.
For that reason, I personally feel that it works particularly well in music in the style of Beethoven or Brahms.

By contrast, the Érard piano has a brightness, elegance, and colorful resonance that feel unmistakably French.
It may seem somewhat lighter in power than Steinway or Bösendorfer, but when used appropriately it can bring a unique charm to a composition.

Finally, I would like to mention Bechstein.

This piano is famous for having been favored by Debussy.
When used as a persona in Suno, it produces a soft, rich tone that almost resembles what one might call a wooden resonance.

There is even a recording of Debussy’s piano works performed on a Bechstein built during his lifetime.
Listening to it, with its soft and sometimes dreamlike resonance, one can almost feel the era in which Debussy lived returning to life.

The persona system therefore allows us to embark on a historical journey through instruments and concert halls without leaving our rooms.
With sufficient mastery, it becomes possible to preserve the memories of that journey as sound.

The fact that concert halls themselves also exist as personas expresses this idea very clearly.

⸻

Combining Instrument and Ensemble Personas

Another interesting creative possibility arises when combining instrument personas with ensemble personas.

For example, one might create a Beethoven- or Brahms-style concerto using the Berliner Philharmoniker persona while selecting a Bösendorfer persona for the solo piano.

Experiences like this strongly stimulate the imagination, and they can also be surprisingly effective methods for producing convincing sonic results.

Similarly, music in an impressionistic style might combine an Érard piano with woodwinds such as Buffet Crampon clarinet or Louis Lot flute, evoking the sound world of late-19th-century France.

A Note on String Instruments

String instruments are somewhat different.

Most historically celebrated string instruments that survive today were built in Italy.
Because performers across many countries and eras preferred Italian instruments, differences tied to national styles or historical periods are less pronounced.

For that reason, when using string personas it is often sufficient simply to understand their tonal characteristics and choose according to musical preference.

⸻

Historical Instruments

It may also be useful to briefly explain historical instruments.

In general, instruments are considered historical instruments when they meet one of the following conditions:
1. Their structure differs from modern instruments of the same type, producing a different sound.
2. Their structure is similar, but differences in size or materials result in a distinct tone.

Examples include:
• Fortepiano
• Harpsichord (Cembalo)
• Baroque and Classical woodwinds
• Pipe organ

These instruments often differ not only in sound but also in appearance and usage compared with modern instruments.

They are often best used in ensembles composed of instruments from similar historical periods.
If you wish to create larger works, combining them with early-music ensembles can produce particularly convincing results.

In fact, there are far more early-music ensembles active today than many people realize.
Because each ensemble specializes in different national traditions and historical repertoires, careful research is the best way to understand them.

For example:

Musica Antiqua Köln
solo Jacob Denner Baroque Oboe

→ German Baroque oboe with string ensemble

Europa Galante
solo Nicoló Amati violin

→ suitable for Italian Baroque violin concertos such as those by Vivaldi

Or more simply:

Gottfried Silbermann Pipe Organ

→ Bach-style organ works

Martin Skowroneck D. Dulcken model

→ Bach-style harpsichord works

Using these effectively may require some knowledge of historical performance practice.

Digital Synthesizer Personas

Finally, we move forward to the modern era and consider digital synthesizer personas.

From a historical perspective, the synthesizer is a very unusual instrument.
Unlike most instruments, it does not possess a single fixed historical identity.

Since its invention, it has appeared in many different musical contexts and continues to evolve.

Its sound palette is also extraordinarily diverse.
Even when certain famous musicians are associated with particular synthesizer sounds, those sounds represent only one possibility among many.

In other words, there is no single definitive sound that can be called “the sound of the synthesizer.”

For that reason, when using synthesizers, it becomes important for the creator to provide a clear musical context.

Selecting a sound is like drawing one contour from a vast ocean of possible tones.

Most digital synthesizers contain well over one hundred different sound patches, each with its own name.
To obtain the desired sound, the correct patch name must be specified.

A similar procedure can be used when employing synthesizers as personas.

The process is as follows:
1. Write the synthesizer name in the prompt.
2. Obtain the instrument’s manual or patch list.
3. Find the desired sound name.
4. Write the sound name in the prompt after the manufacturer and model.

For example:
Digital Synthesizer Kurzweil K2000 Ethereal Strings,

This is a configuration that I have personally confirmed to work.

Compared with other instruments, this area remains largely unexplored, and there may still be many creative possibilities waiting to be discovered.

Conclusion

It is meaningful that this discussion of instrument personas concludes with the synthesizer.

In a symbolic sense, it reflects the essence of personas themselves.

Choosing an instrument persona is not merely a technical operation.
It is an act of deciding within which lineage of sound you wish to stand.

Of course, those who prefer not to think about such questions can simply use presets.
Music can still be created perfectly well in that way.

However advanced AI may become, that choice will always remain in human hands.

How instrument personas are selected and combined is not simply a matter of technique.
It is a direct expression of the creator’s musical philosophy.

The question “Which instrument will you make sound?” ultimately leads to another question:

Which music do you believe in?

Or perhaps:

To which sound do you entrust your feelings?

So then—

Which sound will you choose?
