Practising a passage on a loop

Tap Loop in the player, and cori repeats the chapter the music is currently in, over and over. If the song has no chapters (or you're still before the first one), it's the last 10 seconds before the current position. You adjust the range by moving its two ends on the timeline. That way you can practise a tricky passage until it's solid, without rewinding every time.

Starting a loop

1. 1
   Play the song

   Start the song and jump to roughly the passage you want to practise. In the app, open the player fully for this.

2. 2
   Tap “Loop”

   Web app

   The button with the circular arrow sits in the player bar next to the skip-forward button; in a narrow browser window, next to the bookmark.

   Mobile app

   “Loop” sits below the playback buttons, next to the repeat button.

   The button turns into a display showing the range, for example "0:46–0:53". On the timeline the range is highlighted in colour and has a handle at each end.

3. 3
   Move the ends

   Drag the left handle to the start of the passage and the right one to its end. When you let go, cori plays from the new start or, if you moved the end, from shortly before it. That way you hear straight away whether the boundary is right.

While you drag, a magnifier shows the waveform around the end you're moving, with its time to the tenth of a second. Near the start of a chapter or a bookmark, the end snaps into place there. For fine steps, move your finger (or the mouse) up a little while dragging; in the browser the Shift key works too: the end then moves much more slowly and doesn't snap anywhere. The two ends always stay at least one second apart.

A chapter or bookmark as a loop

Instead of setting the ends by hand, you can also repeat a whole chapter or the part from a bookmark onwards straight away:

"Loop from here" runs from the bookmark to the next chapter start or bookmark that comes at least 4 seconds later, otherwise to the end of the song. How to set bookmarks is described in Playing and practising songs.

The loop options

Tap or click the display showing the range. The options open:

• Range: Set the start and end precisely with minus and plus. Now puts the start or end at the point where the music currently is, handy if you want to set the boundary by ear.
• Step: how far minus and plus move an end: 0.1 s, a Beat or a Bar. Beat and Bar are only available if a tempo is stored for the song.
• Lead-in: With "2 s before", every run starts two seconds before the passage so that you can get into it.
• Pause after each run: none, 2 s or 5 s to catch your breath.
• Build up the tempo: The first run plays at 75 % of the tempo, each further one 5 % faster, up to the original tempo. If you switch it off, the tempo you had set before comes back.

At the top of the options you can see which run you're on. cori remembers the lead-in, pause and step for all further loops on this device (on the web, in this browser).

Ending the loop

Tap the cross in the display, or End loop in the options. The music then simply carries on. If you start another song or close the player, the loop ends too.

If it doesn't work

• "Loop" doesn't respond: The song is still loading. Wait until it plays.
• The loop covers the wrong range: Without chapters, cori takes the last 10 seconds before the current position. Drag the ends into place, or start the loop just after the passage has ended.
• Beat and Bar are missing under "Step": No tempo is stored for the song. The ends then move in tenths of a second.
• The music plays past the end: You jumped beyond the end. Jump back into the range, and the loop kicks in again.
• The repeat button is gone (app): While a loop is running, the loop display sits in its place.
