Visual and Tactile Information in Double Bass Intonation Control

Abstract

Traditionally, the teaching of intonation on the non-tempered orchestral strings (violin, viola, cello, and double bass) has resorted to the auditory and proprioceptive senses only. This study aims at understanding the role of visual and tactile information in the control of the non-tempered intonation of the acoustic double bass. Eight musicians played 11 trials of an atonal sequence of musical notes on two double basses of different sizes under different sensorial constraints. The accuracy of the played notes was analyzed by measuring their frequencies and comparing them with respective target values. The main finding was that the performance which integrated visual and tactile information was superior in relation to the other performances in the control of double bass intonation. This contradicts the traditional belief that proprioception and hearing are the most effective feedback information in the performance of stringed instruments.

Tuning the Hand with Physics and Feeling

“…But consider how a new student needs to learn where the first finger goes. Stickers can help and there is research that supports visual cues (Bergonzi 1997; Lage et al 2007), but I like teaching them to find the first finger with a wiggle string. It is fun and good practice.…”

Coordenação e controlo de movimentos musicais e desportivos: visão dinâmica da cognição e ação

“…Por exemplo, o pianista deve ser ágil no modo como usa os dedos para tocar piano, adotando diferentes velocidades de execução face às músicas que desempenha. Esta manipulação do instrumento "constrange-o" a calibrar e afinar as suas capacidades motoras às necessidades de execução, que variam de contexto para contexto (PALMER, 2006; LAGE, BORÉM, VIEIRA, BARREIROS, 2007). Os mesmos pressupostos podem ser aplicados ao jogador de golfe que tem que "moldar" as suas mãos ao taco ao longo da sua aprendizagem motora, imprimindo assim maior ou menor velocidade de execução no desempenho deste movimento, isto consoante está mais perto ou afastado do buraco (DIAS, COUCEIRO, BARREIROS, CLEMENTE, MENDES, MARTINS, 2014).…”
