Basic information
- Tune type: Slip jig
- Time signature: 9/8
- Key: E minor
- Tenor banjo tuning: GDAE
- Whistle: D tin whistle
Both scores place all 12 measures in four-measure systems, for 3 systems in total. Each of the three parts is placed on its own four-measure system.
D tin whistle: standard notation and fingering
Six circles appear below every note. A filled circle means covered, an open circle means uncovered, and the top circle is nearest the mouthpiece. This setting contains zero notes that are unsupported on a D whistle.
Tenor banjo: standard notation and GDAE TAB
Note names appear above the staff and the TAB appears below it. The strings are tuned G-D-A-E from lowest to highest. Numbers indicate frets, and 0 indicates an open string.
How to practise
- Count 9/8 in three groups: “1-2-3, 4-5-6, 7-8-9.”
- Repeat one measure at a time at a tempo where each three-note group stays relaxed.
- Connect each four-measure line, then play the three parts in A-B-C order.
Source and conversion method
The melody was checked against public setting #10 on The Session.
