Does listening to music affect your heart rate? Introduction: The pulse is an indirect sign of blood pressure and heart beating, which is controlled by autonomic nervous system. Cardiovascular and endocrine responses to musical perception which have been studied largely show different changes depending on the situation of the subject (musical experience, handedness, gender, age) and the type of musical stimulus (sedative, harmony music or rhythmic rock music detailing in simple musical elements like intervals, chords, pitch, timbre; or complex musical structures). In a trial, the heart rate was found to decrease after listening to classical and New Age music but not to change after listening to popular music. The heart rate was found to increase if the music contains a fast beat or slow down if the music encourages physical and mental relaxation. Although changes of heart rate and blood pressure as related to listening to music have been reported by many investigators, the complicated problem is still obscure and need deep investigation to clarify its mechanism.
Safety: When carrying out the experiment make sure you do not put the volume of the music too high as this could dame your hearing and damage your ear-drum. Apparatus: The eqipment that will be needed to carry out the test is: * CD Player * CD's * Pen and Paper to record the results Method: 1. Take the heart rate for one minute, twice without listening to any music. 2. Now take the heart rate for one minute, varying the volume and changing the type of music. Do this twice for each type of music following the reqirements for the fair test. 3. Wait until the heart rate has settled back to normal by allowing 30 seconds rest. 4. Find the average for each part of the test. 5. Record your results. Results: Test 1 (no music)- Heart Rate 0 db Test 1: 77 b.p.m. Test 2: 76 b.p.m. Test 2 (listening to classical music at 20 decibels)
Evaluation: I think that I have answered the question that I was set to find out at the start of the investigation, as I investigated the effects of music on a persons heart rate. Yes, our experiment was fair as we only had two main variables, which were to keep the same volume throughout the test and repeating each segment of the experiment twice. Everything else in the fair test was carried out consistently. The improvements that I would make if I were to redo the experiment would be to do the experiment for a third time and to use an electronic heart monitor and make someone else turn the music on and changing its volume, this is because you are moving and your heart rate is slowly but gradually increasing. I would keep everything else the same. The results were quite accurate. To make it more clear we decided to get an average. The results came out as expected are evident enough to make a firm evaluation that the louder the music the greater the heart rate.

Here's what a teacher thought of this essay
This is a well structured report that covers the necessary areas.
1. The background knowledge section is well researched but the sources need referencing.
2. The tables of data should be compiled into one and the interval readdressed.
3. The conclusion is very brief and makes unfounded large claims.
4. The evaluation shows a good understanding but needs to be written in full sentences.
