## Overview of 'harpwise listen'

The mode 'listen' shows information on the notes you play; depending on settings for display and comment this can be:

- Hole
- Note
- Membership of played note in various scales
- Interval to previous note
- Difference to a reference note, e.g. to practice bends
- Speed of warbles

When playing, you may switch on journal to get a simple transcription of the holes played.

## Usage by Examples:

The wise listens, while your are playing a richter harp of key c and it shows the holes, that you played; green if from the blues-scale, blue otherwise:

    harpwise listen richter c blues

The same, but relying on the defaults for type (richter) and key (c):

    harpwise listen blues

The same, but also showing the notes from the one-chord (chord-i):

    harpwise listen blues --add-scales chord-i --display chart-scales

If you want to follow the chord-progression of a 12-bar blues, you may try

    harpwise listen --scale-progression 12bar

to switch from one chord to the next, every time you press 's'.

To use the RETURN-key, which might be easier to hit, you may try:

    harpwise listen --scale-prog 12bar --keyboard-translate RETURN=s

or use (shorter) '–kb-tr TAB=s' to employ the TAB key. And you may also make this option durable in your config.ini.

If, in addition to the scale-progression, you want one or more licks at hand (e.g. turnarounds), you may give them as an adhoc lick-progression:

    harpwise listen --scale-prog 12bar --lick-prog simple-turn,wade

As an advanced example, assume that you would like to play the minor pentatonic scale in fourth position. However, harpwise only knows it in second position (i.e. starting on -2).

How would you move this scale from second to fourth position?

The first step would be to get the notes of the minor-pentatonic scale:

    harpwise print mipe

then take those notes and shift them from second to fourth position by moving up two fifths up in the circle of fifths.

And because a fifth is 7 semitones (you may check this via: harpwise print intervals), this would be 2 * 7 = 14 semitones.

In addition one would move one ocatve (= 12 semitones) down to reach the lower end of the harp (for more expressiveness): 14 - 12 = 2 semitones.

So we would have to shift the notes of the minor pentatonic scale by 2 semitones to get from second to fourth position:

    harpwise tools shift +2st -2 -3/ +4 -4 -5 +6

Using the resulting holes as an adhoc scale for listen, we would be able to tell harpwise, that we want to play the minor pentatonic in fourth position:

    harpwise listen -3// +4 -4 +5 +6 -6

However, you could get the same effect also like this:

    harpwise listen mipe --transpose-scale +2st

which uses the fact (as explained above), that moving two positions up are just two semitones.

Finally, as a quite technical note: If you find harpwise sluggish or if you get a warning on lagging and lost samples, you may want to experiment with –time-slice:

    harpwise listen c --time-slice short
