Furthermore, the elevated position of the ribs increases rib cage volume and allows for quick phonatory manoeuvres. During phonation, contracted abdominal muscles prevent shortening of the diaphragm and provides the opposing force required for the rib cage to develop strong subglottal pressure in order to increase sound pitch and/or loudness. This would summate with the passive recoil characteristics of chest wall and lungs in preparation for efficient generation of expiratory airflow.

From visual inspection of respiratory kinematics, it has been suggested that, during singing, classical singers contract abdominal muscles at the end of the inspiration phase, which is argued to produce pre-phonatory inward movement of the abdomen. Although the specific role of individual muscles during phonation remains debated, greater activation of abdominal muscles is generally observed during speaking and singing than quiet breathing. However, attempts to identify stereotypical patterns of respiratory kinematics in classically trained singers have been so far inconclusive, and it is unclear how the breathing pattern of classical singers differ from that of untrained individuals.Īccording to the National Association of Teachers of Singing, focus on abdominal breathing is one of the most effective directives when teaching breathing support. Although an agreed definition of the term “support” remains elusive, it is generally considered to involve enhanced abdominal muscle activation, which elevates intra-abdominal pressure and expands the rib cage, thus increasing the length and the pressure-generating capacity of the rib cage expiratory muscles. Experienced singers and teachers commonly refer to the use of abdominal muscle “support” to improve respiratory control and tone quality. Active control of breathing pattern affects the efficiency of the respiratory system and is considered essential in classical singing training for the development of optimal voice performance. movements of rib cage and abdomen) in response to altered task demands. The inward abdominal movements observed in classical singers elevates intra-abdominal pressure and may increase the length and the pressure-generating capacity of rib cage expiratory muscles for potential improvements in voice quality.īreathing patterns during speaking and singing can differ from that during quiet breathing by modification of respiratory kinematics (i.e. This contrasted with untrained individuals, who demonstrated synchronous respiratory movements during all tasks. Despite variations between participants, principal component analysis revealed consistent pre-phonatory inward movements of the abdominal wall during singing. Classical singers substantially altered the coordination of rib cage and abdomen during singing from that used for quiet breathing. In contrast to untrained individuals, classical singers used greater percentage of abdominal contribution to lung volume during singing and greater asynchrony between movements of rib cage and abdomen. During singing, both groups adapted to rhythmical constraints with decreased time of inspiration and increased peak airflow. No group differences were observed during quiet breathing. Several parameters were extracted from respiratory kinematics and airflow, and principal component analysis was used to identify typical patterns of respiratory kinematics.

Here, seven professional classical singers and four untrained individuals were assessed during quiet breathing, and when singing both a standard song and a piece of choice. However, few studies have investigated these patterns quantitatively and inter-subject variability has hindered the identification of stereotypical patterns of respiratory kinematics. This is presumed to prevent shortening of the diaphragm, elevate the rib cage, and thus promote efficient generation of subglottal pressure during phonation. Professional classical singers often advocate for the advantages of an active control of the abdomen on singing performance.
