As this blues song involves lots of improvisation, you can use slash regions to fill bars with rhythm slashes to indicate those players should improvise.
Procedure
-
In bar 1, select the bar rest on the trombone staff.
-
We recommend doing this in the full score, where by default empty bars are not consolidated into multi-bar rests.
-
- Shift-click the bar rest in bar 4 on the trombone staff.
- Press Shift-R to open the repeats popover.
-
Enter slash into the popover.
-
Press Return to close the popover and input a slash region spanning the selection.
-
Dorico automatically displays the appropriate number of slashes for the duration and the current time signature. For example, if this were in 6/8, Dorico would show two dotted slashes in each bar.
-
-
Repeat steps 1 to 5 for the banjo and top piano staff.
Tip
Alternatively, you can select the slash region on the trombone staff and Alt/Opt-click the start of bar 1 on the banjo staff and top piano staff.
-
However, in the recording, only the clarinet plays on beat 4 in bar 4.
-
- Select any part of the slash regions in bars 1-4 on the trombone, banjo, and piano staves.
-
Press Shift-Alt/Opt-Left Arrow to shorten the slash regions back to the end of beat 3.
-
The number of presses required depends on your rhythmic grid resolution .
-
- In bar 5, select the bar rest on the trombone staff.
- Shift-click or Ctrl/Cmd-click the bar rest in bar 16 on the trombone staff.
-
Input a slash region.
-
If these regions were adjacent, the second would have a different highlight color to distinguish them.
-
- Repeat steps 9 to 11 for the banjo.
-
Input slash regions on the cornet staff in bars 5-7 and bar 9 (beat 2) to bar 12.
-
You should now have rhythm slashes throughout bars 1-16 for the cornet, trombone, and banjo. However, the fermatas in bar 16 do not appear automatically in slash regions. Instead, you can input notes in stemless slash voices on those beats.
-
-
Select any part of the slash regions in bars 5-16 on both the trombone and banjo staves.
-
Press Shift-Alt/Opt-Left Arrow to shorten the slash regions back to the end of beat 2.
-
The number of presses required depends on your rhythmic grid resolution .
-
- In bar 16, double-click the trombone staff on beat 3; that is, just after where the slash region ends.
-
Press Shift-Alt/Opt-V until the caret indicator shows you have created a new, stemless slash voice.
- Press 6 to select quarter notes (crotchets).
-
Press Y twice to input two quarter note stemless slash notes.
-
Y inputs default pitches, and is particularly useful for unpitched percussion. Clefs determine the default pitch for pitched instruments, such as G on treble clef staves.
-
-
Press Left Arrow until the caret is at the start of beat 3 in bar 16, then press Down Arrow to move the caret down to the banjo staff.
- Repeat steps 17 to 19.
- Press Esc or Return to stop note input.
Result
You have input slash regions and input notes into stemless slash voices. Using a combination of slash regions and slash voices can be useful when only some bars require specific rhythms, for example.
You can also add slash regions using the Repeat Structures panel on the right of the window, which you can show by clicking Panels , then Repeat Structures in the Notations toolbox.
