The pandemic of COVID-19 led to restrictions in all kinds of music activities. Airborne transmission of SARS-CoV-2 requires risk assessment of wind instrument playing in various situations. Previous studies focused on short-range transmission, whereas long-range transmission risk has not been assessed. The latter requires knowledge of aerosol emission rates from wind instrument playing. We measured aerosol concentrations in a hermetically closed chamber of 20 m3 in an operating theatre as resulting from 20 min standardized wind instrument playing (19 flute, 11 oboe, 1 clarinet, 1 trumpet players). We calculated aerosol emission rates showing uniform distribution for both instrument groups. Aerosol emission from wind instrument playing ranged from 11 ± 288 particles/second (P/s) up to 2535 ± 195 P/s, expectation value ± uncertainty standard deviation. The analysis of aerosol particle size distributions shows that 70–80% of emitted particles had a size of 0.25–0.8 µm and thus are alveolar. Masking the bell with a surgical mask did not reduce aerosol emission. Aerosol emission rates were higher from wind instrument playing than from speaking or breathing. Differences between instrumental groups could not be found but high interindividual variance, as expressed by uniform distribution of aerosol emission rates. Our findings indicate that aerosol emission depends on physiological factors and playing techniques rather than on the type of instrument, in contrast to some previous studies. Based on our results, we present transmission risk calculations for long-range transmission of COVID-19 for three typical woodwind playing situations.

BackgroundThe pandemic of COVID-19 led to exceeding restrictions especially in public life and music business. Airborne transmission of SARS-CoV-2 demands for risk assessment also in wind playing situations. Previous studies focused on short-range transmission, whereas long-range transmission has not been assessed so far.Methods and findingsWe measured resulting aerosol concentrations in a hermetically closed cabin of 20 m3 in an operating theatre from 20 minutes standardized wind instrument playing (19 flute, 11 oboe, 1 clarinet, 1 trumpet players). Based on the data, we calculated total aerosol emission rates showing uniform distribution for both instrument groups (flute, oboe). Aerosol emission from wind instruments playing ranged from 7 ± 327 particles/second (P/s) up to 2583 ± 236 P/s, average rate ± standard deviation. The analysis of the aerosol particle size distribution showed that about 70 − 80% of emitted particles had a size ≤ 0.4 µm and thus being alveolar. Masking the bell with a surgical mask did not reduce aerosol emission. Aerosol emission rates were higher from wind instruments playing than from speaking and breathing. Differences between instrumental groups could not be found, but high interindividual variance as expressed by uniform distribution of aerosol emission rates.ConclusionsOur findings indicate that aerosol emission depends on physiological factors and playing techniques rather than on the type of instrument, in contrast to some previous studies. Based on our results, we present risk calculations for long-range transmission of COVID-19 for three typical woodwind playing situations.

Although music therapy has become a widespread approach used in the multimodal treatment of psychosomatic disorders, this is the first study investigating the perception of music-induced emotions (PoMIE) in patients with somatoform disorders. For the purposes of this study, n = 23 patients (PG) with somatoform disorder (F45) were assessed for PoMIE within an experimental design. Additionally, n = 25 healthy controls were included as a control group (CG) matched for age and gender. A questionnaire including the dimensional (valence, arousal) and the discrete (basic emotions) model were applied to assess PoMIE. At t 0 , the PG gave lower ratings of the emotion happiness, F(1, 48) = 1.24, p < .01, than the CG. Significantly higher ratings of fear were observed in the PG than in the CG. At t 1 , the PG gave higher ratings of happiness for happy-targeted music stimuli than at t 0 , t(22) = 2.35, p < .05. Higher ratings of fear in the PG compared to the CG also persisted after inpatient therapy, t(46) =-2.48, p < .05. The results suggest a lower perception of happiness and a higher perception of fear in the PG. A multimodal, inpatient therapy seems to influence the happiness perception of music-induced emotions in PG. The results may inform the further evaluation of music therapy interventions.
