I wrote and recorded an instrumental song today (see nightfall, box left) using some orchestral instruments.
The only real instruments in the recording are my guitars. I played the oboe, flute, contra bass, bassoon, timpani, concert piano, and pizzicato cellos with my keyboard. In the headphones at least, the instruments sound quite authentic.
After working on this all day about 8 hours, mostly listening and playing around with ideas… I noticed something strange: My heart beat is synchronized to the 150 beats per minute of this song. Is that healthy? It has probably been going like that for hours. No wonder I’m exhausted. I’ve been racing my heart 150 bpm for 8 hours?! Ah, no… it is actually synchronized to 1/2 of the beat, 75 beats per minute.
My resting rate after getting away from the song is back down to 66 bpm.
Here is heart rate chart for exercise targets:
|Age||Target Heart Rate (HR) Zone (60-85%)`|
|Your actual values||Target HR||Max. HR|
Count the beats you feel for 10 seconds. Multiply this number by six to get your heart rate (pulse) per minute.
Count your pulse: ______________ beats in 10 seconds x 6 = ___________ beats/minute
What is a normal pulse?
Normal Heart Rate at Rest
Children (ages 6 – 15)
70 – 100 beats per minute
Adults (age 18 and over)
60 – 100 beats per minute
