4. Using the Thumb-side Tingertips: are there benefits?
4.1. Plucking Into the Strings and Towards the Belly
I have spent the past three years trying these different approaches where the thumb is stretched away from the index. The explanation by Basset was most intriguing for me because of its rare and detailed explanation of the fingertips, so I decided a year to develop and focus on it. As a result, I came to realize that the instruction by Basset, with the help of tips for finger motions given by Piccinini,38 solves most of the issues of playing Thumb-out that was explained by Damiani. After almost two years, I still continue to apply this technique to my playing.
One of the four issues stated by Damiani was that plucking Thumb-out would cause the fingers to be in the way of each other. In Basset’s technique this problem does not exist. When i, m, and a are equally distanced from the strings, the thumb-side fingertip of i touching the strings, they are able to pluck “pushing towards the belly of the lute,” as suggested by Piccinini. As long as these fingers move towards the belly, there is no way that their movements can hinder or be hindered by the thumb. This is because the thumb has its own space to move, and this area of movement does not overlap with area where the other fingers move. In this way, it becomes easier to pluck both of the strings of a course, and the range of tone colors becomes enriched. In the video example 4 (Cf. https://youtu.be/uozROi1LhJM) I tuned one of the string of the 3rd course a semitone lower than what it was originally, in order to demonstrate that I am plucking both of the strings in a course.
4.2. Clashing Strings and Crossing Fingers
Since i, m, and a slide through the strings diagonally and not laterally, clash of strings in a double-strung course is less likely to happen. The palm of the hand is held more or less parallel to the soundboard, and this enables each finger to reach any of the first to fourth courses without being bumping into other fingers. (Watch video example 5 https://youtu.be/1R7ji-PIzSw.) This eventually enabled me to play m-i faster than I was able to previously.
