Miking up a drum kit can be one of the most time consuming and frustrating instruments to record. There are several ways to record drums, from using only one microphone to using one or more microphones in each drum component. 

If we want to record the drums with only one microphone we should use a large diaphragm condenser microphone set to cardioid polar pattern. This kind of microphone gives us clarity and the high frequency response required to record the cymbals and hi-hat. The mic should be placed over the kick drum pointing at the snare drum. Although the microphone is set to the cardioid pattern and is focusing on the snare drum, there is enough spill from the rest of the kit that enables the microphone to pick all the other drum components. If the condenser mic has a -10dB attenuation  switch, it should be switched on in order to avoid distortion in the sound.

Although miking up the whole kit with only one mic is a much quicker process, it is worth spending some time miking up the whole kit as this will produce the best results. The choice of microphone and its position will define the sound of each component. In order to capture a natural drum kit sound, we can use a high quality condenser mic positioned overhead, in front of or behind the kit. The mics used for this purpose include the Neumann U87and KM84, the AKG C414B and C451. Usually the overheads capture enough cymbal sound therefore it won’t be necessary to mic the cymbals individually. 
 
To record the bass drum we want a robust microphone that will have a great low frequency response. The AKG D112 is a large diaphragm dynamic microphone and is specially designed to record the kick drum. If the front head of the kick drum has been removed or if it has a large enough hole in it, the mic should be placed inside close to the beater head about halfway between the centre and the edge. In addition to this microphone we can use another dynamic microphone further away from the beater head. Trying different positions of the mics is always a good idea in order to get the best sound.

Although the snare drum can be recorded with a condenser microphone like an AKG C451, the most common approach is using a dynamic mic like the Sure SM57. When using an SM57 we get a fatter and bigger sound than when we use a condenser. It is also much easier to control the signal as dynamic mics are less sensitive. It is a good idea to use two mics on the snare: one on the top; and one below to capture the sound created by the rattle. The mic on the top should be placed near the edge because a fuller range of overtones is present in this area. This approach also minimizes the changes of it getting it. The microphone positioned below the snare should be placed about 20 cm away from the rattle halfway between the edge and the rattle. When using a mic below the snare, its polarity should be switched to the opposite polarity of the one on the top.

Usually there is enough hi-hat sound captured by the overheads but we can mic it up individually for better clarity and control. To record the hi-hat we can use a small diaphragm condenser mic, placing it about 10-15cm over the outside edge of the hi-hat. The mic should be perpendicular to the the hi-hat pointing down. In order to avoid the sound created by the snare the mic should be placed on the side that is furthest away from the snare. 
  
In order to mic up the tom-toms we can use a similar approach to the one used on the snare drum with dynamic mics positioned over the rim pointing to the centre of the head. The rear of the mic should be angled up to reject the sound produced by the cymbals (note that the cymbals radiate sound in a figure of eight pattern above and below the metal plate). In terms of microphones we can use a dynamic microphone like the Sennheiser E604.

After using Royal Roost as the first song to improvise, we moved to something slightly different. Cantaloupe Island is a song by Herbie Hancock that doesn't follow the jazz blues chord progression. It uses 3 different chords that repeat every sixteen bars - 4 bars in Fm7, 4 bars in Db7, 4 bars in Dm going back to Fm7 for the last four bars. Cantaloupe Island is one of the first modal jazz compositions therefore it uses modes instead of chord progressions as an harmony frame.

In order to improvise in this song I have started by learning the melody. After that I started practising the modes that I could use over the chords in the song. The modes that can be used to improvise over the chords in this song are: F Dorian mode over the Fm7; Db Mixolydian over Db7 and D Dorian over Dm7.

We can also use major triads to improvise over each chord creating interest and tension within our solos. The major triads that can be used over Fm7 are Ab and Bb, Cb and Db can be used over Db7, and over Dm7 we can use F or G. another method that can be used to improvise is Pentatonic Substitution. We'll use the minor Pentatonic scale to improvise. There are four different minor Pentatonic scales that can be used over Fm7 - F minor, C minor, G minor and Bb minor. Over Db7 we can use Bb minor Pentatonic and Db min Pentatonic. The minor Pentatonic scales that can be used over Dm7 are D minor, A minor, E minor and G minor.

In order to improve my improvising skills I'll practice each of these chords, modes and scales individually. Once I have mastered them I'll try to start singing each mode on the second degree of the scale. I'll practice the triads and their inversions. I will also compose some solos using these concepts and I'll sing them over the backing track. I am planning to do this over the next couple of weeks.



 
I have worked on the Mixolydian and Dorian modes. Although I have practiced the modes while playing the piano and the guitar I still feel that I am not able to sing both modes accurately without any accompaniment. I can sing each mode if I am given the root note but I still find it quite hard singing a Mixolydian and changing to the Dorian mode.

In order to practice these modes in an improvisational context I have composed a solo outlining the chord changes. In order to outline the chord changes I have used the correct modes over each chord (Dorian over a minor seven chord and Mixolydian over a dominant seven chord) changing from a third to a seventh, a root note to the root note of the following chord or a fifth to a fifth. Composing solos will give me ideas of what I can do and if I practice different solos I will be able to use different ideas to improvise.

When I sing the melody I composed it sounds really good but I feel like I still want to sing the root note when the chord changes. I’m not used of singing a third or a seventh. I am going to listen to different versions of Royal Roost and transpose some of the ideas that they use for soloing. I will also try to compose some more ideas, practice the modes and try to improvise while using a backing track.

Recording an acoustic guitar is a complex task and there are a lot of different factors that we should have in mind before recording. First of all we must choose an acoustic guitar that suits the song as two different guitars can have very distinctive sounds. As mentioned in a precious blog, it is important to use new strings when recording guitars and tune the guitar before each take.

If the acoustic guitar has a pickup that is always one advantage as it could add some colour to the sound. If the guitar doesn’t have one it is good idea to use a piezzo pickup and place it in different parts of the guitar to try to get the best sound. Miking up an acoustic guitar always produces better results. Although we can use an SM 57 to record an acoustic guitar that is not the best approach. Condenser mics are much
more sensitive and pick up much more high frequency detail. 
 
Purists will usually pick a small-diaphragm condenser microphone for its greater high frequency accuracy. In terms of polar pattern, the cardioid pattern tends to suit smaller rooms better whereas omni-pattern mics would be better in larger rooms with natural reverb and better acoustic characteristics. 

The position of the microphone is crucial when recording. In live situations for example, it is normal to see the mics placed very close to the sound hole of the acoustic guitar because the main concerns are level, separation and the avoidance of feedback. When we are recording acoustic guitar we need to have a totally different approach. It is true that when we play the acoustic guitar most of the sound energy comes directly out of the sound hole. However, the sound we hear is coloured by the body resonances of the guitar. Therefore, if the mic is used too close to the guitar, the direct sound produced by that part of the guitar will be more dominant. This is an important concept to have in mind when recording with more that one mic.
    
If we are using only one microphone, the most common approach is to set up a mic around 40cm from the guitar, aiming it at the point where the guitar’s neck joins the body. This will usually produce a well-integrated and balanced sound as the levels of direct and reflected sound will be about right and the sound coming from the sound hole won’t be too strong as the mic is not pointing directly at it. 

If we are using more than one mic, we should keep the condenser microphone at the position mentioned before and place other mics around. If we place a microphone over the musician’s shoulder, this will produce a sound similar to the sound we hear when we play the guitar. We can also place a microphone pointing to the neck of the guitar but the best thing is exploring and placing the mic in different places until we find the best sound.

For my first solo performance I have decided to perform one of my own songs. I decided that it would be a good idea to perform one of my latest songs as I have adopted a different practicing method.  This was the first time I was paying attention to some details while I was writing this song and I have tried to fit the vocals better into the rhythm and chords played by the guitar.

When I wrote Save me from hell, I was inspired by the breaking up of one of my best friend’s relationship. I was aware of the way he was feeling and I have tried to include feelings like anger, desperation or insanity in the way I sing. As the song progresses to the chorus, there is a build up that is related to someone getting agitated.

Once the song was written and finished, I have tried to apply the breathing techniques learnt in my singing classes and I have tried to work on my placement. Once I felt confortable singing the song accompanying myself on the guitar, I have started focusing on the performance itself. My girlfriend is a Drama teacher and as she has a Degree in Performing Arts, I though it would be a good idea to ask he for some help. I usually find it quite hard to connect with the songs I sing, as I have never had Drama classes at school. It was quite interesting working with her on this song.

We started by reading the lyrics and talking about what they mean. After that she read the lyrics as if she was telling a story, and acted it as a monologue. Furthermore, we worked on putting myself into character and I have sung the song a few times. We recorded a couple of performances and I noticed that I managed to get into character. It sounded better than the version I was originally singing and I suppose it gave me confidence.

On the day of the performance, I decided to warm up my voice properly and play the song a few times to get in the zone. Once we went in the class I had to wait for other people to perform and I think it has affected my concentration a little bit. Once I started performing I felt that there were some problems with the sound and changes in volume. I don’t know if the sound was too loud and the sound guy changed anything but I felt that I didn’t have full control of the microphone. At some point I was going to move away from the mic as I was going to sing louder but the volume of the microphone got lower. Therefore, I felt like I was constantly adjusting. I believe that I should have spent longer sound checking to avoid similar situations.

Although I felt like I could have got more into character and perform it with more emotion, I think that it was a good performance. I want to work more on my performing skills and how to get more into the song, transmitting more emotion and feelings to the audience.

Recording vocals is a very complex process as a good vocal sound can make the difference between an average and a great song. The most used microphones for vocal recording are condenser microphones. However, dynamic microphones are commonly used when recording vocals for trash metal or other genres that include screaming. If you are recording live with a band and you don’t have access to an isolated room for vocal recording, it is a good idea to record vocals with a dynamic microphone and overdub the vocals later on using a condenser mic.

Considering that you are ready to record vocals, there are a few factors you should think of. The position of the microphone is one of them. It is important to place the mic away from the walls. You should also try to avoid placing the microphone in the centre of the room as the sound waves are usually in phase at this location, which tends to exaggerate the room resonances. In order to reduce popping it is a good idea to use a pop shield between the singer and microphone. It should be placed around 10 cm from the microphone.

Most large-diaphragm microphones have its own shockmount suspension, which can be extremely effective in reducing unwanted noise. This kind of suspension is used to isolate the microphone from the stand reducing the amount of noise cause by mechanical vibrations. 

In terms of polar pattern, most sound engineers use the cardioid polar pattern as it is more sensitive to sounds  coming from the front than from the back. When recording, it is a good idea to use an analogue compressor. This helps evening the signal levels and could avoid some distortion in some loud parts of the song. You should avoid using an EQ during the recording process. Usually the EQ is added during the mixing process.
