it's similar to being a vocalist, except instead of it coming out of your throat, you're controlling it just in the air and you don't really have a point of reference; you're always relying on your ears and adjusting constantly.
Tas ir līdzīgi kā vokālistam, izņemot to, ka tas nenāk no rīkles, bet to regulē gaisā, un tā īsti nav tāda atskaites punkta. Jūs vienmēr paļaujaties uz savām ausīm un visu laiku pieregulējat.
