4 chords only

Can a song be made up with this chord progression?


Key G minor.


Bass code:
G
E7
F
D7


For example playing notes consecutively:


Bass G and G A B D
Bass E and G A B D
Bass F and F G A C
Bass D and F G A C


All B and E are flat since the key is G minor.

How does the Shure SM59 microphone operate?

Referring to patent US3989905, assignee Shure Brothers Inc, inventors C. Roger Anderson, Eduard A. Rusch, Charles E. Seeler.


Mechano-pneumatic shock mount means that air molecules are automatically sent to the back of the diaphragm in order to cancel handing noise.
The cartridge is supported by 2 compliant toroidal supports.
There is a diaphragm at the end of one of the chambers.
Adjustable pressure build up? and adjustable air leak is used to make the SM59 one the less vibration immune microphones.


Here is a small extract from the patent description:


Assuming a shock force is applied to casing 100 in the direction of the arrow F (the patemt document shows a force in the direction of the axis of the microphone towards XLR connector), casing 100 momentarily moves to the left relative to housing 30, thereby creating a slight pressure in cavity 90. A small percentage of shock force F is coupled to housing 30, thereby through shock mounts 122 and 132 so that transducer assembly 28 tends to move to the left relative to diaphragm 12 and voice coil 24, which are resiliency mounted  on transducer assembly 28. This relative movement between transducer assembly 28 and voice coil 24 would normally produce an electrical output from the microphone. However, the pressure in cavity 90 tends to move diaphragm 12 to the left in step with the movement of transducer assembly 28, so that the relative movement between voice coil 24 and transducer assembly 28 is minimized.
Pressure from cavity 90 is coupled to side 15 (back of diaphragm) of diaphragm 12 through rear entry channel 94 in the manner previously described in order to keep diaphragm 12 in step with assembly
28.
By using components of the type described and adjusting the components in the manner taught, the output of the microphone due to mechanical shocks applied to casing 100 in a direction parallel to axis 20 may be substantially reduced over a wide of frequencies.

PS


It is impressive how low handing nose this microphone has.
And how great the sound quality is.

A timing exercise

A rather interesting exercise is tapping 1/4ths (bass drum) with the left hand while playing the riff melody of the Italo disco song Face to Face - the Twins

An unusual arrangement of Bach's fugue BWV1000 for organ instead of harpsichord

It was played last week to Vicky on an 80's Yamaha portable keyboard and she really liked it thinking it sounds out of this world.


She prefers an organ arrangement to a lite one as the sound has an ethereal continuity.


Here is a harpsichord arrangement:

An email has been sent today to Sony Classics in Germany on whether they would like to hear an idea for an unusual Bach's masterpiece arrangement.


By the way, here is another interesting Bach's music with major 7th intervals with respect bass, played on lute:
Lute sonata no 1 BWV 1001
