"Tech" was once a loosely defined but serviceable term used to describe a particular charting philosophy. Over time, it stopped being useful for three distinct but related reasons: it accumulated too many overlapping and contradictory meanings to describe anything precisely; the tech/dump binary it depends on doesn't reflect how modern charting actually works; and the "technical" skillset in Etterna's difficulty calculator reinforces the word's vagueness rather than clarifying it. If the goal is clear discussion about charting, it's better to stop relying on labels like "tech" and instead describe what a chart is actually doing.
Some terminology exists because it describes a set of ideas, others persist because they're convenient, despite being loosely defined. In Etterna, "tech" has been in the latter category for a while. Most players and charters use this term to hand-wave at many attributes: complexity, awkward patterns, weird snaps, and mostly, accurate charting (which we can define as a literal note-to-sound representation).
Because these attributes overlap so heavily, the same chart can be labeled "tech" for entirely different–and sometimes contradictory–reasons. Tech didn't become controversial because it was misused, but because it accumulated overlapping definitions.
Terminology matters in Etterna because community language and terminology shapes how people learn, what packs get played, what charts get recommended, and ultimately what can be valued as "good charting." When a central term stops describing identifiable properties and starts carrying personal judgement, it becomes difficult to have clear discussions about charting or explaining ideas to newer charters.
To first understand why such an important term ended up so fragmented, we need to understand the charting philosophies it grew out of.
Early DDR and StepMania pad content wasn't really built around the idea that each sound needs to be represented as a note. Charts were often abstract: meaning they matched the energy, phrasing, and feeling of a track. You would see sections of a track represented by patterns that created a sense of groove where the track might have been doing something completely different. Some of these patterns were used for coherence, and the "essence" of the chart came from consistency and pacing rather than something accurate to the track.
Keyboard charting evolved with a similar, but different incentive. Now that there was more precision available, it became much more common to chart notes to discrete sounds present in the track. This style wasn't universally respected at first, and would go by what was defined as "karaoke steps". The keyboard community persisted with this style, and it wasn't long before this was the main difference between keyboard and pad charting. The old pushback against these charts is part of why this conversation exists in the first place: charting culture split between "express the music" and "transcribe the music."
Over time, the keyboard community would normalize this transcriptive form of charting. What used to be a stylistic choice gradually formed into the default expectation for how charts should be made. As this shift happened, the language around charting had to stretch to cover more ground. There was a need for terminology that could describe both how a chart was created and how it felt to play to the player.
"Tech" began to fill that gap. For a while, it served as a relatively coherent label for conventional, accurate charting. Notes were placed with clear intent, typically aligned closely with distinct sounds. The structure of these charts tended to be strict, predictable, and easy to justify. Say someone were to ask why a note was placed where it was, the answer was usually straightforward.
As long as "tech" referred to this charting philosophy, it carried explanatory value. The problem is that it didn't stay confined to that role. As charting evolved, the term was slowly pulled away from its original meaning and applied to increasingly unrelated ideas. That drift is where the fragmentation began.
At some point, "tech" gradually stopped meaning "this chart was created using a conventional, literal transcription of the music" and started meaning "this chart feels weird to play." This change didn't happen all at once, but it did come with consequences. Once tech became a description of feeling, it could be applied to almost anything: unfamiliar patterns, uncomfortable transitions, weird snaps, unconventional notetypes (like rolls/lifts), or any element that disrupts a player's preferred sense of flow.
This is where we start running into contradictions. If tech is now taken to mean "doesn't flow," then a smooth, flowy chart should not qualify as tech. Yet, many players still describe some smooth charts as tech. Furthermore, if tech is taken to mean "accurate," then charts that deliberately add notes beyond an accurate approach shouldn't qualify either. However, many expressive charts–where sounds are represented through patterns–are still labeled tech, often because they're difficult to read or contain enough variety to resist a simple classification.
"Tech" no longer describes how a chart is created and is instead used to describe friction: how the chart interacts with, or clashes against, the player. That can be useful as a personal shorthand when talking about one's own experience with a chart, but it works poorly as shared terminology. When a word means "this feels odd or uncomfortable to me" rather than "this chart was created in a specific way," it becomes difficult to use for clear analysis or explanation because it becomes tied to subjective experience.
This drift isn't just one problem though. It's three distinct problems that tend to get mixed together, which is part of why discussions about tech go in circles. The rest of this piece tries to address each of them separately.
One of the more interesting failures of "tech" shows up when it's defined as "following the music as closely as possible." If that's the goal, then a strictly accurate approach isn't always the best route. Sometimes the most faithful way to represent a track isn't a note mapped to a single sound, but instead a phrase represented through multiple notes–a pattern used to capture how a sound moves or is emphasized over time.
In that sense, a dump can sometimes be more musically faithful than a conventionally accurate chart. If accuracy means "I can point to the sound for each note placed in this chart," that's one model. If accuracy means "the chart expresses the song's phrasing and feeling," that's another. Once both models are treated as valid, the idea of "tech" collapses in on itself. It's now being used to describe two opposing ends of the same spectrum.
Once you accept this second model, the definition of tech begins to mean multiple things. Now "accurate" can involve abstraction and expression. The word is trying to separate two ideas that aren't separable in practice anymore.
This overloading is also fed from outside the rhythm game sphere. In other gaming contexts, "tech" typically refers to unconventional mechanics, niche strategies, or bits of meta knowledge that players discover on their own–something that isn't immediately obvious, something you have to learn or exploit through experience. When that meaning carries over, "tech" begins to imply that a chart is tricky or requires unintuitive techniques to play correctly. The focus moves even further away from charting intent and toward how unfamiliar it feels to play.
The result is a term that has quietly absorbed several incompatible definitions at once: note-to-sound accuracy, musical faithfulness, pattern complexity, and player discomfort. These aren't the same thing, and using one word for all of them means it can no longer reliably describe any of them.
Many discussions lean on the idea of tech versus dump, as if they're opposites. It was a pretty simple concept to grasp: tech is clean and accurate, dump is expressive and flowy. One is note-to-sound, the other is pattern-to-sound. These distinctions made enough sense when charting styles began to become more siloed, especially when dump charting began to gain popularity. However, this concept doesn't really align well with modern Etterna charting.
These days, charting mixes both of these philosophies. Look at Scintill's Minipack 3, for example. Most players might write these charts off as tech, and call it a day. But looking closer, you can see pattern-based vocal expression that goes beyond the strict note-to-sound "technically accurate" approach. This is a deliberate choice used to represent phrasing and texture in ways that a purely literal approach can't. At the same time, those same charts often return to an accurate approach when clarity is important. The result is a chart that doesn't fit cleanly into either category and instead moves between them as needed. This reflects intentional decision making by the charter, not confusion in the chart itself.
Experienced charters are fluent in these different techniques and apply them selectively. A chart might rely on accurate charting in one section for clarity, then shift into more expressive, dynamic patterning elsewhere to emphasize texture or momentum. These transitions are intentional and reflect an understanding of how different techniques can be combined to represent music faithfully. Collapsing this into a single label flattens what's actually happening. Two charts described as tech may share very little beyond the fact that they resist easy categorization, and the tech/dump binary can't describe this without inventing increasingly awkward exceptions.
There's a deeper issue here that makes the "opposites" framing fall apart: the two words are being used to describe different aspects of a chart. "Dump" is often used in the context of the structure of a chart, while "tech" is used more to describe how the chart feels to play. When the terms aren't describing the same kind of thing, treating them as opposites doesn't work.
The phrase "tech dump" makes this failure explicit. On its surface, it doesn't really make sense: if these two terms are meant to be opposites, combining them should be nonsense. The fact that players and charters use the term anyway is less of a mistake and more an admission that these labels no longer work. In practice, "tech dump" tends to be used for charts that appear abstract and follow the pattern-to-sound approach while still feeling musically coherent, or for dumps that include unusual patterns or some unconventional structure. These are real distinctions that people are trying to gesture at, but the phrase itself doesn't clarify which of these qualities is being referenced. Rather than resolving this ambiguity, the term compounds it.
In the context of Etterna's difficulty calculator, charts are broken down into seven distinct skillsets. Most of these are fairly straightforward and describe specific kinds of patterns or physical demands. One of them, however, stands out from the rest: technical.
For many players, this skillset becomes a stand-in for what they think of as "tech." Most of that comes down to convenience. In practice, "technical" in the calculator doesn't describe a single, well-defined type of charting. Instead, it functions as a catch-all for anything that doesn't fit into the other six skillsets.
This effectively means the technical skillset acts as a remainder bin. Mixed skillset charts, variety-heavy charts, novelty; charts that don't resemble a clear single skillset archetype are all likely to be labeled technical. The label doesn't tell you what the chart is doing so much as it tells you that the calculator doesn't have a more specific place to put it.
Over time, this reinforces the same ambiguity surrounding "tech." Players encounter wildly different charts that all score highly as technical and begin to associate the skillset with difficulty, unfamiliarity, or discomfort rather than any concrete principle. The harm here is specific: "technical" ends up depending entirely on the player's lack of familiarity with a pattern rather than any property of the chart itself. Eventually, "tech" stops functioning as a meaningful category and becomes shorthand for "everything else."
At this point, "tech" does almost no descriptive work and instead functions as shorthand for a set of unspoken reactions. Depending on the context, it might mean "this chart might feel uncomfortable," "this isn't a scoring chart," or "this isn't something I enjoy playing." These meanings are rarely stated outright, but they're often what the word is actually being used for.
Because of that, disagreements about tech are frequently not about how a chart is created at all. They're about what kinds of difficulty players respect, what kind of charts they might enjoy playing, and sometimes what they believe should be valued as "good charting." The term absorbs these judgements and presents them as if they were objective properties of the chart itself. Once a term starts to carry personal values and preferences in this way, it stops being useful for analysis.
There isn't a clean one-word replacement for "tech," and that's the point. Looking for something to substitute this terminology assumes that charting can still be summarized with a single label. Modern charting doesn't really work that way, and trying to force it into one usually obscures it more than it explains.
That being said, some terms are still useful when they're applied narrowly. One example being "conventional." If used carefully, it can describe charts that follow a standard, accurate approach; charts that rely on familiar ideas and are easy to justify in terms of note placement. Additionally, this describes how a chart is made, not how it feels to play or whether it's tricky. It might be a limited term, but it points at something concrete.
More generally, the most productive alternative to "tech" is simply being more specific. If the point of your chart is a strictly accurate approach, say that. If the point is abstract expression, say that. If the difficulty of your chart comes from something unconventional, describe what is unconventional about it. Sure, the descriptions will be longer, but they communicate what matters.
Letting go of "tech" isn't about pretending these distinctions don't matter. At some point we have to admit that one word can't carry all of these meanings anymore. Charting hasn't become more difficult to talk about, but it's now specific enough that we actually have to say what we mean.
