Relation between music and body conditionsSergej Zwaan

System System that learns how

people react to music(classification)

Uses this knowledge to affect body conditions

(reinforced learning)

System

Musical elements like;bpm, pitch and volume

Body elements like; heartbeat, blood pressure and temperature

Issues• A certain BPM can

affect a certain heartbeat (increase or decrease)

• A start and end heartbeat per reading are necessary.

• People will react differently on different songs

Input/output Classification

Output: Random Song (BPM)

Input: Start heartbeat

Input: End heartbeat

System: reading song 1

1

2

3

Read start heartbeat

Xs

Play random

song

Read end heartbeat

Xe

If Xe - Xs >

0

IfXe – Xs =

0

IfXe – Xs <

0

Put the song into class:Increase

Put the song into class:Stabile

Put the song into class:Decrease

Classification Different classes can be made for example:

Class heartbeat 90 80: Abba – Mama Mia Michael Jackson

– Thriller

Class heartbeat 90 81: Run DMC – It’s tricky Adele – Chasing

pavements

Class heartbeat 70 75: Snow Patrol – Run

Class ……….. etc

Classification The system has to

be run with a lot of different people

A huge amount of classes can be created ( about 900 classes)

Songs can appear in multiple classes

How to use the classes to affect body conditions?

Getting the heartbeat from 90 to 60Use a song from Class 90 60

Use a song from Class 90 80 + a song from Class 80 60etc

Getting the heartbeat from 90 to 60 The combination of classes with the

lowest amount of songs will be rewarded.

When a class hasn’t got the proper result like for example: class 90 80 will only get to 85, a second class will automatically be added, in this case class 85 80.
