This guide applies to six-hole woodwind instruments such as the Irish tin whistle (penny whistle), low whistle, or Irish flute. It explains the basics of the whistle as an instrument and guides you through all of its scales and keys. Letter notes and fingering charts will also help understand how to read tin whistle tabs, which can be very useful for those unfamiliar with sheet music notation.

Scales in traditional Western music generally consist of seven notes and repeat at the octave. Notes in the commonly used scales (see just below) are separated by whole and half step intervals of tones and semitones. The harmonic minor scale includes a three-semitone step; the anhemitonic pentatonic includes two of those and no semitones.

  1. Play with notes and scales. Now that you've learned a bit about notes and scales, spend some time creating your own patterns. You can try out how your patterns sound with different collections of notes by changing the Tonic and Scale settings. (These terms are explained in the Advanced topics lessons but you can already play with them here!). You can also create beats that will play in sync.
  2. That’s right that that pentatonic scales only have 5 notes per octave, but the scales in the diagrams span more than 1 octave, and each red dot is a root note in a different octave. You’ll see that there are 5 notes from one red dot to the next, but you want to use all the octaves you can in your current position on the fretboard.

Tin whistle basics – keys and scales

New Notes - Scales Of Motion

Unlike some classical music instruments (i.e. clarinet or flute), a single tin whistle can play only one standard (diatonic) musical scale of seven notes. Actually, two scales, by using a special cross fingering for an additional note (you will read more about it soon). It means that you will need several different whistles to cover every song in its original key. Or if you are likely to play with a band, you probably need different whistle keys to match the other musicians and their instruments.

If you are just getting started, you probably want to follow the fingering guide and notes for a whistle in the key of D. It is the most common key and probably the very first whistle you should get as most tunes and songs are played in this key. At least in terms of Irish traditional music.

Holes & fingers placement

Regarding fingers position, you should cover the holes with three middle fingers of both hands. As a rule of thumb, your strong hand goes to the bottom and the other one on top. There is also a tutorial on this website thatexplainshow to hold a tin whistle correctly in more detail. You may want to check it out as well as other useful whistle lessons.

How many octaves a tin whistle can play?

The tin whistle has two octaves (usually named lower and upper). And while the fingering is the same for both of them, you reach the upper octave just by blowing harder. There is an exception for the key (root) note itself, which is available in 3 octaves. So, on a D whistle, you have a note D in its third octave too.

Understanding tin whistle finger charts guide

The simple graphic below should help to avoid any confusion about reading all of the charts on this page and any other tin whistle notes guide that you may come across.

The dark circle represents the holes covered with your fingers. The light circle is for open holes. There are also uncommon cases where you may want to half-cover the hole for semitones. The plus sign means that the note is in the upper octave, the fingering is the same, but you blow harder to achieve it.

Tin whistle fingering chart – key of D

Music Notes On The Scale

D is the most common key among both high whistles and low whistles.

Playing “C natural” note on a D whistle

You should have in mind that every whistle, regardless of its key, has another note that doesn’t naturally belong in the scale, but can be played too. This special note is usually referred to as the crossing note or the flat 7th. On a D whistle, this is note C, which is a note between B and C# (notes 6 and 7). That way, it means you can play another scale (key) on the same whistle. So, having a note C available on a D whistle, you can play both D and G scales.
Below is the fingering chart for the “special” C note. There are a couple of finger position alternatives, as the pitch of that note varies depending on the whistle, and also its lower/upper octave.

Tin whistle fingering chart – key of C

C is a very common whistle key for an Irish whistle, but there are a couple of brands that offer a low C whistle too. By using a special note B flat (Bb) on a C whistle, you can also play the F scale.

A whistle finger chart

Whistle in the key of A is a medium-sized, somewhere between a high and a low whistle, sometimes it’s called Alto A whistle. By using special fingering for the note G on an A whistle, you can play D scale too.

B flat (Bb/A#) whistle finger chart

Bb whistle is also a common tin whistle key, offered by many manufacturers. By using special fingering for the note G#, playing Eb scale is possible.

B whistle chart

Whistles in the key of B are rare and not available among most of the whistle makers. The special fingering can be used for the note A, providing a way to play E scale.

E flat (Eb/D#) whistle chart

Whistle in the key of E flat (Eb) is a many players’ choice. And that applies to both high and low whistles. Its specific pitch usually provides a slightly more sharp and crispier tone than a regular D whistle by the same brand. By using special fingering for the note C#, you get Ab scale available fro playing too.
