"In tempo" has you play along at the piece's tempo — Klavissimo listens and scores whether you hit the note at the right time.
The count-in leads you in
Before the recording starts, the count-in counts you in — 1 or 2 bars, set in the player ⚙ under "Count-in". After the count-in, play the first note on the one: the accented click is the one. In 6/8, 9/8 and 12/8 the start of each group of three eighth notes also clicks a little higher, so in 6/8 that is the fourth eighth note.
The accented click is the one — then the recording runs.
Metronome while playing
Want more than just the count-in? The metronome button in the control row or the "Metronome while playing" switch in the player ⚙ keeps the metronome clicking through the whole exercise, not just during the count-in. Both are the same setting.
Playing several times in a row
Before you start, the passes button in the bar at the bottom sets how often the exercise runs: "1×", "3×" or "∞" (loop). Every exercise and every piece starts at 1×, and Klavissimo remembers your choice for each exercise and each piece. The count-in only plays before the first pass; after that you carry straight on in time, and so does the accompaniment. Every finished pass is scored and saved like a run of its own, and a pass with no note at all doesn't count. "Stop" ends all passes, and while you play the button shows which pass is running, for example "2/3". The loop ends by itself after two passes without a note. Ensemble parts that aren't scored, the introduction and "Follow your playing" don't offer the choice. With "Real piano", it applies to "Keep the tempo": nothing is scored there, the ♩♩♩ question appears once at the end on the result page, and the loop keeps going until you press "Stop".
Changing the tempo
For a piece of your own or an imported one, you set the tempo via the "♩ =" field in the practice excerpt — freely adjustable between 20 and 300, with "Original: …" showing the piece's original tempo alongside. Built-in exercises, on the other hand, always run at their fixed tempo — there's no tempo field there; in 6/8 and 3/8 the header gives that tempo in eighth notes, for example "♪ = 120", and in alla breve (2/2) in half notes, for example "𝅗𝅥 = 60".
Pieces that change tempo
If a piece changes tempo in the score, say from Lento to Allegro, Klavissimo follows the change, as long as the score file contains a tempo number for it. The "♩ =" field is then the base tempo: change it and every tempo in the piece speeds up or slows down in proportion. The count-in uses the tempo at the start of your range, and after that the metronome follows each change. If your range starts in a different tempo, the base tempo is shown after it at the top, for example "♩ = 60 · base tempo ♩ = 138". Gradual changes such as "rit." are up to you; playback and scoring stay at the tempo of that section. A piece you imported before Klavissimo understood tempo changes keeps playing at one tempo; importing the same file again picks up the changes.
What "in tempo" means for timing
Klavissimo compares not just whether you hit the right key, but also whether you hit it on time — your result marks that roughly as "early" or "late". Exactly how that scoring breaks down is covered in the article on the result.
Good to know:
The hint levels (gentle/medium/strict) from the player ⚙ only apply to "Note by note" — "In tempo" has no leniency ladder; here it's simply whether you were on time.
