"In tempo" has you play along at a fixed 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.
The accented click is the one — then the recording runs.
Metronome while playing
Want more than just the count-in? The "Metronome while playing" switch in the player ⚙ keeps the metronome clicking through the whole exercise, not just during the count-in.
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.
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.
